dovecot - Nov 2004 - dovecot and outlook express and large messages

Hi

I have been using Dovecot 0.99.11 and 1.0-test52 on a server with about
2000 accounts. All has been working good until a few days ago. Now I'm
stuck and can't work out whats going on. 

The problem seems to be only with Outlook/outlook express clients. If
the mail is large with an attachment its fails. After you hit the send
and receive button after a while Outlook express gives the error "Your
POP3 server has not responded in 60 seconds". Network activity seem to
be minimal between the client and the server. There is no log entry out
of the ordinary to say what went wrong. I have tried out a number of
changes to the dovecot.conf file, none make any difference.

Thanks for any help.

Regards
Daniel Rowe

Hi

Dose dovecot have problem working on a eth0:1 alias type interfaces? I
just wondering if this could be my problem?

Dovecot would do the authentication correctly and send small email but
as soon as any load was put on it like downloading a mail with a large
attachment it would fail. All network traffic would stop. No errors in
the logs. As soon as I move the service to listen on a non alias
interface eth0 all works fine. Very strange. I have taken a good look at
our server to check that is not anything. I'm pretty sure we are good. I
have also rebooted the box to see if that would fixed it which it
didn't.

Regards
Daniel

1.0-tests have had similiar problems before, and I guess there can 
still be some problems (have to try to find out those..). But did this 
happen with 0.99.11 too?
