[Dovecot] Timeouts connecting via POP3

[Don O'Neil]

I have SSL setup, but I'm not specifically using it myself when I get the
hangs.... I'll have to set the log up and post the results next time it
happens..

Here's the config output though:

Do you use SSL? It hangs before it can log in? What does Dovecot's logs show
(set auth_verbose=yes)?

There's one bug related to that:

v1.0.rc15 2006-11-19  Timo Sirainen <tss at iki.fi>
	- Potential SSL hang fix at the beginning of the connection

And what do you use as passdb/userdb? Post the whole dovecot -n output?
