Oct 22 16:15:32 lxmhs52 dovecot: auth: PLAIN(?,xx.xx.xx.xx): Request 0.21 timeouted after 150 secs, state=2
state 2 = "waiting for auth data from client", so what it means is that the client sent:
AUTH PLAIN
and then just didn't do anything.
Since it is mostly the same IP repeating I'm assuming it's a client issue. Is that correct? What could cause this? Can we safely ignore it?
You can safely ignore it. It should have been logged with "info" level and only with auth_verbose=yes. Although I guess the message could be a bit nicer. This is better I think: http://hg.dovecot.org/dovecot-2.1/rev/49bb6cc43d03
