List Owners Guide for ListServ

LISTSERV is a lab wide e-mail list service used to collaborate and share information with a large group of people. This service allows customers to create and maintain e-mail lists through a web interface https://listserv.fnal.gov. This guide is a reference for list owners to help answer the most asked questions for list ownership via the web interface.

To manage a list via e-mail, please refer to either of these locations.

• For some common email commands, you can refer to our Listserv website https://listserv.fnal.gov and select List Owners - Managing Your List Through E-Mail

Getting Started

How do I manage my lists?

1. Log into LISTSERV https://listserv.fnal.gov
2. Select Manage Your Lists
   
3. On the Login Required screen, enter your e-mail address and password and click Log In.
   

4. The List Dashboard shows all lists you are an owner of and can perform the various management tasks to configure your lists. Under Select List, select the list you want to manage. For help with any topics, simply click on the question mark next to it.

What is the "List Title" and how do I change it?

The List Title is a one-line description, maximum of 100 characters, of the list which is assigned when the list is created. This description is automatically included in the mail message sent to new subscribers. This description also appears in the online web archives listing.

To change the List Title:

1. Under List Management in the menu click on List Configuration
2. Select the list you want to manage under Select List
3. Select the Descriptions tab
4. Edit List Title.
5. Click on Update at the bottom of the page
   

How Do I manage List subscribers?

1. Select the list from the menu and select Subscriber Reports.  You can review current subscribers, add or remove a single subscriber, or click on Bulk Operations to add or remove multiple subscribers.

2. If running Bulk Operations, the input file must be a plain text file (with the extension of .txt) and must contain one address per line, optionally followed with a space (or TAB) and the subscriber's name. The input file cannot contain quotes. For example:

emailaddress firstname lastname

emailaddress firstname lastname
emailaddress

emailaddress firstname lastname

Do I need to subscribe to my own list?

If you want to receive the messages sent to the list, then yes, you will need to subscribe to your own list.

How can I subscribe one list to another or set up nested lists (sub-lists)?

LISTSERV offers "super-lists" and "sub-lists".

With a super-list, the membership of all the sub-lists is added and duplicates are suppressed. The super-list is a normal list with its own archives, access controls, etc. List owners may convert a standard list that they own into a super-list, but they may only add other lists that they own to the Sub-Lists= setting

For more information see L-Soft Documentation  Click on the LISTSERV 16.0 List Owner's Manual link and see Section 12.13.12 Super-Lists and Sub-Lists.

Exporting, importing and removing listserv subscribers in bulk?

Some owners may want to export a copy of their subscribers as a backup or import a list of subscribers from another list. While there is not a command to move or transfer listserv subscribers, you can export subscribers from your old list and then import them into your new list. Owners can also use this to remove malformed subscriber addresses or easily update the list subscribes in bulk.

Exporting subscribers from a list

1. Log in to the Fermi Listserv Web Interface at https://listserv.fnal.gov
2. Select Manage your lists
   
3. In the box under Show Lists enter the list you want to import the subscriber into and click on Search, then click on the list name to select.
   
4. On the side menu, select List Management\Subscriber Reports. From the pull-down menu under Report Format, select CSV Format then click Check All under that. Then click Update
5. Select Save on the popup download window and save the file to your computer (remember the location you saved it to)
   
6. Open the .csv file with Excel
7. Delete the entire first row and any columns after A. You should only have column A with the user’s name and email address.
   
   
   
8. Select File\Save As then select the format as Text (Tab Delimited) (*.txt).
   
9. The resulting file will look like this when opened with Notepad
   
   
   
   

Importing subscribers to a list

1. Note: To import subscribers into a list, you will need a plain text (.txt) file. Each line of the file should contain ONLY the email address of the person, a tab or space, and the person's name. You must have only one email address per line.
2. example:
3. johndoe@google.com John Doe
   marydoe@Indiana.edu Mary Doe
4. When importing subscribers, you can only import the email address and name. All other modified settings must be set on each subscriber account after they are imported via the subscriber management page.
5. Log in to the Fermi Listserv Web Interface at https://listserv.fnal.gov
6. Select Manage your lists
   
7. In the box under Show Lists enter the list you want to import the subscriber into and click on Search, then click on the list name to select.
   
8. On the side menu, select List Management\Subscriber Reports then click on  Bulk Operations next to Add Subscriber
   
9. Select Choose File and navigate to the location of your .txt file and open it, then click on Import.
   
10. You will receive a message concerning the number imported and any errors.
    

Remove All Subscribers

To remove all subscribers and replace them with a new imported list.

1. Access Listserv Management at https://listserv.fnal.gov.
2. Go to the Subscriber Reports section.
3. From the Select List, find and select your list
4. Scroll down to the Report Format section, and just below that click Check All, to select all the current subscribers .
5. Scroll all the way down to the bottom of the page, and you will see the Delete Subscribers button.
6. Don’t check the box for Send Email Notification, so subscribers won't be notified they are being removed.
7. Click the Delete Subscribers button.
8. Click the Update button.
9. Then you should be able to import your new list of users.

How do I manage automated messages?

To create or change automated messages sent to subscribers when they are Welcome, Farewell, subscribed, removed, modified, etc:

1. Under List Management in the menu click on Mail Templates
2. Select the list from the menu and select Mail Templates
   
3. Select the mail template you want to customize the automated message for.
4. Make your modifications.
5. Click Update
   

· There are three possible places to change this "YOU ARE NOW SUBSCRIBED" message.

o The SIGNUP1 or "You are now subscribed to the &LISTNAME list" template which includes/imbeds the $SIGNUP template.

o The ADD1 or "You have been added to the &LISTNAME list" template which includes/imbeds the $SIGNUP template.

o The $SIGNUP or "Standard message to new subscribers " template.

· When a user subscribes to a list, LISTSERV sends the SIGNUP1 message.

· When a list owner manually adds a subscriber to a list, LISTSERV sends the ADD1 message, unless "Do Not Notify the User" has been selected.

· By default, both the SIGNUP1 and the ADD1 messages imbed the $SIGNUP message by including a .im $SIGNUP command in those message templates.

· To eliminate the SIGNUP1 and the ADD1 messages, edit those messages as described below.

o Add the .QQ command as the first line of each template. This will cancel the message.

How can I stop my list from sending messages (prevent new postings from being sent)?

Example: My list keeps sending the same message over and over again (looping). How can I stop my list from sending any messages until I get the problem fixed?

You can prevent new posting from being processed by issuing "hold" command. This will hold all messages until a "free" command is issued.

1. Under List Management in the menu click on LISTSERV Command
2. Select the list you want to manage under Select List
3. Under New Command enter: Hold LISTNAME
• Click Submit
4. You can also just click on the Sample Commands and it will auto populate the New Command window for the selected list.
5. To release the hold and resume emails under New Command enter: Free LISTNAME
• Click Submit

General Support Information

What are the most commonly changed configuration?

Detailed information for key words can be found in the List Keyword Reference for LISTSERV 17.0.

Help can also be found under List Management and clicking on Show Keyword Categories.

List Owner Information

Owner = EmailAddressOne,EmailAddressTwo....

Who can subscribe to the list?

Subscription =

• Open,Confirm -> Anyone can subscribe to the list. They must confirm their address with an "OK" response. No list owner intervention is required.
• By_Owner -> New users are not allowed to subscribe. Their requests are forwarded to the list owner.
• By_Owner,Confirm -> Same as "By_ Owner" with the addition that the subscriber must first confirm their address with an "OK" response.
• Closed -> New users are not allowed to subscribe. Their requests are "bounced" back to the sender, i.e., the list owner does not see the requests.

Who can post (send) messages to the list?

Send =

• Public,Confirm -> Anyone can send to the list.
• Private,Confirm -> Only list members can send to the list.
• Owner,Confirm -> Only the owner can send to the list. Messages are "bounced" back to the sender.
• Editor,Hold, Confirm
     Editor = editors_emailaddress -> All messages are sent to the editor for approval.

Should the listname or archives be seen by non-subscribers of the lists?

Confidential =

• No -> Display the listname.
• Yes -> Keep the listname confidential.

Who can view the online archives?

Notebook =

• Public -> Anyone can view the online archives.
• Private -> Only list members can view the online archives.
• Owner -> Only the list owner can view the online archives.

Who can review the list of subscribers?

Review =

• Public -> Anyone can view the list of subscribers.
• Private -> Only list members can view the list of subscribers.
• Owner -> Only the list owner can view the list of subscribers.

To whom should the replies go?

Reply-to =

• Sender,Respect -> Replies are directed to the original sender. The original "Reply-to", if any, is kept.
• List,Ignore -> Replies are directed to the list address. The original "Reply-to", if any, is ignored and discarded.

Listserv "X-Report-Type:" field found in the mail header

List owners may receive an error message that reads:

>> The enclosed message, found in the listname mailbox and shown under the spool ID xxxx  in the system log,  has been identified as  a possible delivery error notice for the following reason: "X-Report-Type:" field found in the mail header

The list owner should click on the attachment included with this message. The attachment will give them more information about the specific error.

The attachment may read:

This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
janedoe@example.com

In this example, the attachment tells the list owner that the message was unable to be delivered to the recipient. This could be because the subscriber is over quota or the address is no longer valid. If the list owner continues to receive this error message, it is best to remove the subscriber from the list.

This error message occurs when a message cannot be delivered to one or more recipients. The recipient's email address may be incorrect

What is the purpose of Loopcheck=NoSpam?

A list owner who sends to multiple lists may wish to add the Loopcheck = NoSpam setting to their LISTSERV configuration file to prevent themselves from being identified as a possible spammer. We would only recommend adding this setting to moderated lists, where the moderator can then prevent spam messages from being sent to the entire list.

How do I restrict my list so that only individuals with AN FNAL email address can send to it?

It is possible to use the wildcard symbol to limit postings to @fnal.gov addresses only. The following option in the list header configuration will limit postings to the list owner and anyone with a @fnal.gov address:

Send= Owner,*@fnal.gov,Confirm

All my messages to my list are pre-approved (Send=Editor,Hold,Confirm) and I am getting bombarded with spam. Is it possible to also use the Send=Private option to limit postings to list members only?

We recommend you set your list to:

Send = Editor,Hold,Confirm,All

This will require the spammer to confirm that they sent the message. See How to Decrease Spam to LISTSERV for details on using these settings.

How can I delete unwanted messages from the list archives?

1. Open the list archives page.
2. Find the messages you wish to delete.
3. Click the Delete button to the right of the message.

How Do I Setup Different Types of Lists (moderated, public discussion, etc.)

For information concerning different types of lists see the List Owner's Manual section 12.13 Setting Up Lists for Specific Purposes for more detailed information.

How do I setup a Public Discussion List? (Anyone can subscribe & post)

Set the list configuration settings to:

Subscription = Open,Confirm
Send = Public,Confirm
Notebook = ......,Private

This configuration will:

• Allow anyone to subscribe to the list (Subscription = Open).
• A confirmation e-mail will be sent to the subscriber (Subscription = ...., Confirm).
• Anyone can to post directly to the list (Send=Public).
• A confirmation e-mail will be sent to the sender (Send = ...., Confirm).
• Only list members can view the list archives. (Notebook=....,Private).

See the List Owner's Manual section 2.13 Setting Up Lists for Specific Purposes for more detailed information.

How do I setup a Private Discussion List? (Anyone can subscribe with owner approval, but only list members can post)

Set the list configuration settings to:

Subscription = By_Owner,Confirm
Send = Private,Confirm
Notebook = ......,Private

This configuration will:

• Subscription requests are forwarded to the list owner (Subscription=By_ Owner) after the requestor confirms that they sent the request (Subscription=....,Confirm).
• Only list members can post directly to the list (Send=Private). Other messages will bounce to the sender.
• Only list members can view the list archives. (Notebook=....,Private)

See the List Owner's Manual section 2.13 Setting Up Lists for Specific Purposes for more detailed information.

How do I setup a Basic Edited (Moderated) List? (Only listed editors can post; all other messages are sent to the first editor for approval)

A basic edited list allows the Editor(s) to send directly to the list.

All other messages are sent to the first editor listed for approval or rejection. If you need to have more than one person approving the messages, see "How do I set up a moderated list?" below.

Set the list header settings to:

Send = Editor,Hold,Confirm,All
Editor = UserName@fnal.gov,firstname2-lastname2@fnal.gov

where UserName@fnal.gov is a valid e-mail address. The first editor must be a real address, not an access-level such as "Owner".

This is called an "edited" list. More than one editor may be listed, but only the first one listed will receive copies of messages for approval. All editors may post directly to the list.

See the List Owner's Manual section 2.13 Setting Up Lists for Specific Purposes for more detailed information.

How do I setup a Moderated List? (Only listed editors can post; other messages sent to multiple moderators for approval)

A moderated list is similar to an edited list or announce-only list, but allows multiple persons to approve or reject the messages.

The editor(s) can still send directly to the list.

All other messages are sent to the moderators for approval or rejection.

Set the list header settings to:

Send = Editor,Hold,Confirm,All
Editor = UserName@fnal.gov,firstname2-lastname2@fnal.gov
Moderator = UserName@fnal.gov,someotherfirstname-someotherlastname@fnal.gov

where UserName@fnal.gov is a valid e-mail address. The first editor must be a real address, not an access-level such as "Owner". All moderators must also be listed as editors. All editors are not required to be moderators.

This list will "load-share" meaning, the first message will go to UserName@fnal.gov for approval, the second message will go to someotherfirstname-someotherlastname@fnal.gov, etc.

To have all the messages go to all of the moderators each time, add "All" before the list of addresses:

Moderator = All,UserName@fnal.gov,someotherfirstname-someotherlastname@fnal.gov

Note: The All, must be before the list of moderators.

Once the message has been approved by one of the moderators the message is sent. Other attempts to approve the message will indicate that the message has already been approved. It will not be sent more than once.

See the List Owner's Manual section 2.13 Setting Up Lists for Specific Purposes for more detailed information.

How do I setup a Self-Moderated List? (Members can post directly to the list but non-member's posts are sent to an editor for approval)

A self-moderated list allows list member to post directly to the list but non-member's posts are sent to an editor for approval.

Set the list header settings as shown below. Be sure to include the listname in parentheses on the Editor keyword.

Send = Editor,Hold,Confirm,All
Editor = UserName@fnal.gov, (listname)

where UserName@fnal.gov is a valid e-mail address and listname is the name of your list. Be sure to include the parenthesis. The first editor must be a real address, not an access-level such as "Owner".

See the List Owner's Manual section 2.13 Setting Up Lists for Specific Purposes for more detailed information.

How do I setup a Private Moderated List? (All postings from list members are forwarded to the editor/moderator for approval and all postings from non-members are rejected)

A private moderated list causes all postings from list members to be forwarded to the editor/moderator for approval and rejects all postings from non-members.

Set the list configuration settings to:

Subscription = By_Owner,Confirm
Send = Private,Confirm

Editor = UserName@fnal.gov,....
Notebook = ......,Private

Default-Options = Review

Using the web interface, select List Management > LISTSERV Command. If you own more than one list, use the pull-down arrow in the Select List: field to select the correct list.

In the Command: field type the following command:

QUIET SET listname REVIEW FOR *@*

Press Enter Command.

The editors will need to set themselves to NOREVIEW or they will have to approve their own postings also.

This configuration will:

• Subscription requests are forwarded to the list owner (By_ Owner) after the requestor confirms that they sent the request (,Confirm).
• Only list members can post to the list (Send=Private). Other messages will bounce to the sender.
• All postings from new list members will be sent to the editor/moderator for approval (Default-options - Review).
• All current list members will be set to the Review option (QUIET SET listname REVIEW FOR *@*) and thus their postings will also be sent to the editor/moderator for approval.
• Only list members can view the list archives. (Notebook=....,Private)

See the List Owner's Manual section 2.13 Setting Up Lists for Specific Purposes for more detailed information.

How do I setup an Announce-only List? (Only the list owner(s) or specific email addresses can post to the list)

Only the list owner(s) or specific email address can post to an announce-only list. 

Set the list configuration settings to:

Send= Owner,Confirm
Reply-To= firstname1-lastname1@fnal.gov,ignore

Or

Send= UserName@fnal.gov,Confirm
Reply-To= firstname1-lastname1@fnal.gov,ignore

where UserName@fnal.gov and firstname1-lastname1@fnal.gov are valid e-mail addresses.

With this set up:

• Only the list owner(s) (or UserName@fnal.gov) will be able to post directly to the list.
• The reply-to will always be set to firstname1-lastname1@fnal.gov (the ignore setting).
  This could be a special account set up to handle responses.

This setting will require the list owner to confirm all postings. This helps to prevent hackers from forging the list owner's e-mail address. This may also help prevent mail looping problems.

See the List Owner's Manual section 2.13 Setting Up Lists for Specific Purposes for more detailed information.

How do I post to an Edited or Moderated List?

Whether you are a list member or the editor or moderator, simply send the message to listname@list.fnal.gov

Messages posted from the list editors will be automatically sent on with no approval required. If the list configuration headers are set to Send=Editor,Hold,Confirm a confirmation message will be sent to that editor. This is for security to ensure that a hacker has not faked the sending address.

All other messages will be sent to either the first listed editor, for a basic edited list, or the list moderators, for a moderated list.

See the List Owner's Manual section 15 Moderating and Editing Lists through Email for more detailed information.

I am the list editor/moderator. How do I approve the messages?

If the list header settings are set to:

Send=Editor,Hold,Confirm,xxxx

The editor/moderator will receive the following message:

For security reasons, the ESO-WSS-TEST list has been configured to request positive confirmation of messages posted to the list. You must now confirm that the enclosed message did originate from you. To do so, simply reply to the present message and type "OK" (without the quotes) in the text of your message, or click on the link below. If this does not work, or if the message did not originate from you, then contact the list owner for assistance.

To APPROVE the message:

https://listserv.fnal.gov/scripts/wa.exe?OK=1253F41E&L=LISTNAME

The above message will include a copy of the message submitted for your approval.

To approve the above message, either

1. Click on the URL provided
2. Reply with just "ok" as the body of your message (only if HOLD is specified on the Send keyword)
3. Or select List Moderation
   
1. Review the message
2. Select the action
3. Click Submit

1. Click Moderate next to the list you wish to moderate
2. Follow on-screen instructions. If you select List Moderation directly from the toolbar, you must select All Moderators and Refresh to see the messages waiting your approval.

The posting will appear to come from the original sender, Username@FNAL.GOV

You can also edit the message and resend it to the list, but the posting will appear to come from you, the editor, Editorname <EditorUserName@fnal.gov>

+++++

If you always need to edit the messages before sending them on you can change the list configuration headers to (remove the HOLD):

Send=Editor,Confirm,xxxx

See the List Owner's Manual section 15 Moderating and Editing Lists through Email for more detailed information.

As the moderator of a list, I get the message for approval plus the posted message. How can I stop getting two copies?

As the moderator, you are not required to also be subscribed to the list. Simply unsubscribe yourself from the list.

How can I delete a list?

Fill out the request form on our Listserv webpage https://listserv.fnal.gov

I get an email message every time someone subscribes to my list. How do I stop this?

Set the list header settings to:

Notify=no

Or set the Quiet: option for some of the list owners in the Owner= header setting, for example:

Owner=Username1@fnal.gov,Quiet:, Username2@fnal.gov

See the List Keyword Reference for LISTSERV 17.0 for more information.

Can I set my list to require subscribers to renew their subscriptions on a regular basis?

Yes, this can be done using the Renewal header setting. You can also have LISTSERV probe for bad e-mail addresses.

See the List Keyword Reference for LISTSERV 17.0 for more information.

How do I ban some email addresses from sending or subscribing to my list?

This can be done using the "Filter" list keyword in the list header. In the list headers set:

Filter = Also,e-mail-address-to-filter

where: e-mail-address-to-filter is the address to be banned.

See the List Keyword Reference for LISTSERV 17.0 for more information.

How can I "hold" or "free" my list?

Under LISTSERV Command, enter the command Free listname or Hold listname.

How can I completely remove the welcome message?

1. Select the Mail Templates
2. Select the Welcome template
3. At the top of the Contents section add a new line and type: “.QQ" (without the quotes). This will cancel the message.
4. Click Update

How to Decrease Spam in LISTSERV

Anti-Spam: Why Set Your List to Send=Public,Confirm or Send=Private,Confirm

By adding the Confirm option, the sender will be required to confirm their message before it is posted to the list.  This reduces the problem of spammers posting to your list by faking the return address.

What difference will your users experience?

When someone sends an email message to your list, LISTSERV will respond to the sender with the following message:

To cut down  on spam,  the LISTNAME  list has  been configured  to request
positive confirmation  of messages  posted from  email addresses  not currently
subscribed to  the list.  You must now confirm that the enclosed  message did
originate from you. To do so, simply reply to the present message and type "OK"
(without the quotes) in  the text of your message, or click  on the link below.
If this  does not  work, or  if the message  did not  originate from  you, then
contact the list owner for assistance.

To APPROVE the message:
https://listserv.fnal.gov/scripts/wa.exe?OK=2E1C8995&L=LISTNAME

The sender must either reply to the message with OK (as described above) or click on the link provided in the email.

If they choose to click on the link, LISTSERV will return:

Anti-Spam: Tips to Decrease Spam to the List

Send Keyword Settings:

• Send = Private,Confirm <- Recommended default setting for non-moderated lists.
  Only members of the list can send to the list.
• Send =Public,Confirm
  Anyone can send to the list.
• Send = Public,Confirm,Non-Member
  These options allow anyone to post to the list, but if the sender address is not subscribed to the list, the sender must confirm their message before it is posted to the list. List members do not need to confirm their messages.
• Send=Owner,Confirm
  Only the list owners can send to the list.
• Send=Username1@fnal.gov, Username2@fnal.gov,Confirm
  Only the email addresses listed can send to the list.
• Send = Editor,Hold,Confirm,All
  All messages must be approved by the editor (moderator) before being posted to the list.
• Send = Service,Confirm
  Service = *fnal.gov,*.fnal.gov
• Filter=also,*@list.fnal.gov

Setting the above Send and Service keywords will limit the allowed senders to fnal.gov addresses.
Setting Filter=also,*@list.fnal.gov disallows messages sent with the fake email return addresses of other LISTSERV lists.
Details about the service keyword are available at:

https://www.lsoft.com/manuals/17.0/listkwd/kservice.html

Additional Keyword Settings:

· Confidential = Yes <- Recommended default setting for lists.
Setting the Confidential command to Yes, removes the name of the list from the public list-of-lists.

· Subscription = xxxxxxxx,Confirm
The Confirm option requires the sender to confirm their subscription.

· Moderated or Announce-Only lists. You also set your list as moderated or announce-only.

· More tips can be found at Tech Tip (LISTSERV) - Issue 3 - 2007 by L-Soft.

How can I stop an active spammer from posting to a ListServ List?

1. Select the list and select Subscriber Management
1. In the Email Address and Name section, type the email address that is sending the spam.
2. Select Do Not notify the User
3. Click the Add Subscriber.
2. Select Subscriber Reports
1. Check the box next to the email address you just added
2. Under Mail Status select No Mail from the pull-down list
3. Under Restrictions select No Post from the pull-down list
4. Click on Update

Send test emails to the list to verify you are receiving good emails.

Spam from specific addresses does eventually stop so you can add this configuration and then at a later date remove it once the spam has ceased to help keep your list configuration clean if desired.
