Dear Sir:
On a test system we installed 6.3 and after looking at the new KDE and other 
desktops decided not to deploy SL 6. 

Now the problems began.
We installed 5.7 on test system and allowed it to find internet settings 
automatically.   The system was updated using yum to latest.   We noticed 
that KMail was always off line.   On our production systems KMail can be set 
to ON or OFF line by use of drop down.   Not on this on test system.  
Internet works fine and we can send mail but no way to get mail as its off 
line and "get mail" is grayed out.
There is a lot of stuff on internet about KDE 4 and this problem but nothing 
works and things they were trying to do not exist in SL 5.7.
Any scheme to fix this problem - I suspect that problem has to do with 
internet availability.   I appears to be up.
??
