[Dovecot] Dovecot hung or what?
Here is my first major problem with dovecot. I am running rc15 on
FreeBSD 6.1. I run dovecot supervised by DJB's daemontools.
I run only the pop3 service.
A colleague informed me that pop3 service was simply not responding.
They could not rcv mail. When I checked the server, tail-ing
dovecot.log, here is what was scrolling:

After this, dovecot was now answering as expected.
1. What could the problem be?
2. How can I reproduce it.
PS: This has never happened ever since with the previous versions.

Hello List,
I have a dovecot server working with sendmail in virtual sites configuration, it is working really well. Now I have to work with pop3s (ssl) and I would like to know if it's possible to define something like:
Server = example.com Address = 1.1.1.1 Certificate = certificateDirPath
I will appreciate any suggestion, my dovecot version is 1.0
Thanks in advance.

I basically see the same with rc15, using imap. It doesn't respond to anything anymore.
Clueless what is causing it though, I'll try to get some debugging info.

Did you have auth_verbose=yes? It might have shown something more.
Also you could have tried to do telnet localhost pop3 and try to login manually, and see where it got stuck.
- What could the problem be?
I'm guessing dovecot-auth got stuck. What passdb and userdb do you use?
- How can I reproduce it.
Dunno. :)
