[Dovecot] Dovecot (IMAP) Hangs sometimes

[Mario Gomide]

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
     ssl_listen = *:[another port]
}
Then I commented the listen line, and things got better, but not good enough
yet. Strange, uh?

I know I should not be using webmail locally via SSL. But I got less errors
like that. Altough, I know once I get the problem solved, I can go back to
the correct solution.

Just for the record: My mail server is running super fast! The problem
happens only at specific moments, twice a day, only.

Otherwise, what's the other configuration that could be eating up resources?


BTW, I got plenty of CPU (2xQuadCore 3.0) and memory (32GB).
