I'm running dovecot rc13 now on sparc64, freebsd 6.1-STABLE
When i'm connected with my 5 accounts to my dovecot imap over ssl/tls server i get the following message in my logs: Nov 18 15:25:47 Info: imap-login: Disconnected: Inactivity: rip=x.x.x.x, lip=x.x.x.x, TLS My client (thunderbird) then re-requests my password for only one of the 5 accounts.
Try if this patch helps:
http://dovecot.org/list/dovecot-cvs/2006-November/006895.html
Can't really think of anything else. It means that from Dovecot's point of view the client didn't send authentication command at all. It didn't help :( the only difference because of the patch is that i don't get the inactivity error anymor in the logs, instead of that I _only_ get the following message:
Nov 19 12:18:10 Info: IMAP(user@domain): Disconnected
For the sake of clarity; this and the previous error happens after being logged in for quite a while (about 25 minutes) on randomly one of my five imap mailboxes.
