kmail- cannot start process pop3

[neidorff]

Hi All,

Well, I'm really stuck and need help.  I'm grasping at straws to
figure out what caused the problem I am having.  Here is the problem
(I have posted this in other threads. I'm still trying to find a
solution)  Running FC3, KDE 3.3.1-2 and kmail 1.7.1.  I'm using qmail
(from qmailrocks.org) to recieve mail for all users on my network. 
Everything has been working great up to a couple of days ago.  Then,
mail stopped coming in or going out.  In checking the logs, I found
that yum had installed exim and that messed everything up.  So I
stopped exim and now mail is coming in and going out as normal.

I read my mail on the same computer that the mail server runs on. 
When I start kmail, it posts an error dialog:  "Cannot start process
pop3" and then does not bring in my mail.  I used netstat to verify
that tcpserver (from qmailrocks) is listening on port 110. I can
"telnet localhost 110", log in and list my mail, so I know that the
pop server is alive and working (plus other users can get their mail).
 I ruled out my firewall (turned it off, briefly and got the same
error message.  I also ruled out hosts.deny and hosts.allow, since
they are empty.

I'm guessing that something that yum installed/updated on my system
has caused my problem, but I don't know.  Its only a guess.  Here is
what yum installed when the problem began (when this problem occurred,
I turned the automatic updating by yum off.  I do learn from my
errors)

Will someone PLEASE help me figure out what has caused this error and
what to do to correct it?  I'm at a loss.

Many, many thanks,

Mark
