The specific moments are at about 9:40 am and 2:30 pm. Exactly when I have most of my users connecting simultaneously (when they arrive in the morning and back from lunch break). At these exact moments, dovecot hangs. Anyways, I took a look at http://wiki.dovecot.org/LoginProcess. I increased the

Exactly! I agree with you! I used to have webmail connect locally via unencrypted IMAP on port 143, but the problem occurred even more frequently. So I thought that it could be dovecot not being able to work out both protocols... I had it like this: protocol imap { listen = 127.0.0.1:143

Interesting But I used to have dovecot work with the same number of users (up to 9,000) and with the default number of fole descriptors with no problems... I can give it a try, though. I can't upgrade dovecot until Red Hat releases a new version. On Thu, Jan 7, 2010 at 11:35 AM, Steffen Kai

Hi there! I'm using Dovecot 1.0.7 in RHEL 5.4 64bits as a IMAP/POP3 server. Dovecot authenticates users against an AD server via kerberos (pam configuration) and clients connect to it via IMAPs and POP3s with SSL. Webmail is in localhost and connects locally also with SSL. All is fine and people
