popa3d Catatonic?

Hello,

 

I’ve been using popa3d happily since 0.5.9 on a RH Linux 9 machine. I’ve been trying to get it to work on an identical RH9 machine that doesn’t seem to be working. It compiles fine and executes well enough, and I see port 110 open up when it becomes activated… yet when Outlook tries to connect to it to pop mail, Outlook returns the error message:

 

Task 'mail.domain.com - Sending and Receiving' reported error (0x800CCC0F) : 'The connection to the server was interrupted.  If this problem continues, contact your server administrator or Internet service provider (ISP).'

 

This was happening with 0.6.3 and now with the most current 0.6.4.1 as well. There is no firewall between the two machines. The server is definitely reachable. There is no antivirus software or any of the other “desktop software” things people generally associate with this particular Outlook error code. I Googled it and come back with half a dozen other people with a similar error, but most of them were not in English and I couldn’t get anything useful out of the discussion threads.

 

I’m assuming that there’s something glaringly obvious wrong on the server, but I’m not real sure where to look at this point. There don’t appear to be any error messages coming from the popa3d daemon which is under the control of xinetd. The port is open, the IP is reachable, I can connect to port 110 with telnet – just nothing good comes back! L

 

Any advice would be much appreciated!

 

Thanks,

SK (sean-Q/cum/4HTbdWk0Htik3J/w@public.gmane.org)

Oh my god - THIS LIST IS ALIVE!

UGH, RedHat.

Make sure you have PAM support enabled, and all of that.

Make sure the "dummy user" popa3d needs is defined with an empty "home
directory", etc.  It's usually popa3d.

Make sure you have PAM entries allowing popa3d to service authentication
requests (or whatever Redhattian nastiness is required).

Try this:

telnet hostname pop3
USER user
PASS pass
(where user and pass are valid login identities)

For security's sake, it might be better to do it on localhost.

Try the telnet test.  I expect you'll see a fault straight away.  Chances are
the popa3d is crashing because of runtime problems.

I imagine you have authentication issues.... with RedHat, there are always
"issues" like these.

No initial +OK and no -ERR either?

This means that your problem is in your xinetd and possibly TCP
Wrappers (tcpd) configuration.  It has nothing to do with popa3d
itself, and it also has nothing to do with user authentication.

It is likely that there're error messages from xinetd or tcpd in
/var/log/messages - please check that.
