Brad,
Let me certain that I understand you.
~/.thunderbird/gr6o2z18.default/ImapMail/exchange.csusb.edu is my path
to a set of IMAP email entries, extension msf for most
cat -v INBOX*.msf | less
yields nothing like a header
However, one of the files has a name without extension, INBOX-75
cat -v INBOX-75 | less
does seem to contain text that could be parsed and extracted by the
script you kindly provided. However, this single file (-75) is not
complete in terms of the historical epoch I need. All of the relevant
email is kept on a remote proprietary Microsoft cloud email server that
will respond to standard IMAP requests from standard open systems
clients, such as Thunderbird -- one is not forced to use a proprietary
Microsoft product as a client. It appears that the .msf files somehow
contain IMAP instructions to retrieve earlier epoch email from the
server. If this is the case, elucidation would be appreciated. What I
have found is:
From http://file.org/extension/msf
The MSF files that are used by these email programs do not contain the
actual contents of the email message that was sent or received using the
email service. These files only contain an index of the messages and the
message mail headers and summaries. The Earthlink and Mozilla email
applications both use the .msf file extension for this purpose.
When I do process a msf file with cat -v and hunt for subject via less,
I find:
(71ED1=3ae99)(2F6CC=Cloud webinar presentation (was: Re: (no subject\)\))
but no actual subject field -- merely a text string that only contains
the phrase subject as above.
The MSF files that are used by these email programs do not contain the
actual contents of the email message that was sent or received using the

Again, all of this could be avoided were there a screen capture method
that contained an OCR that would allow me to paste into a word
processor, LaTeX text, etc.
