I'm using dovecot 2.1.12-r1. When remote imap server rejects connections then I can't login into account and MTA can't deliver emails to maildir also.
I'm attaching snippets of logs: 2012-12-15T18:05:43.072594+01:00 meteor dovecot: imap-login: Login: user=marcin@mejor.pl, method=PLAIN, rip=2001:470:1f0b:1ab3:50af:bef4:6918:78ad, lip=2001:470:1f15:1b61::2, mpid=32533, TLS, session=<T0GGKOfQCQAgAQRwHwsas1CvvvRpGHit> 2012-12-15T18:05:43.442598+01:00 meteor dovecot: imap(marcin@mejor.pl) <T0GGKOfQCQAgAQRwHwsas1CvvvRpGHit>: Error: imapc(imap.wp.pl:143): Server disconnected: Connection reset by peer 2012-12-15T18:05:43.442598+01:00 meteor dovecot: imap(marcin@mejor.pl) <T0GGKOfQCQAgAQRwHwsas1CvvvRpGHit>: Error: imapc(imap.wp.pl:143): Authentication failed: Disconnected from server 2012-12-15T18:05:43.442598+01:00 meteor dovecot: imap(marcin@mejor.pl) <T0GGKOfQCQAgAQRwHwsas1CvvvRpGHit>: Error: imapc: Command failed: Disconnected from server 2012-12-15T18:05:43.442598+01:00 meteor dovecot: imap(marcin@mejor.pl) <T0GGKOfQCQAgAQRwHwsas1CvvvRpGHit>: Error: user marcin@mejor.pl: Initialization failed: Namespace 'xxx-wp-pl.': imapc: LIST failed: Internal error occurred.

Would be nice to have fewer and nicer error message lines of course.
This isn't problem for me.
I'd like to ask is this behavior correct?
You're using Dovecot as simple imapc proxy without local mails? Then yeah, what else could it really do?
Here is problem, I'm using local mails also!:) So when remote imap server doesn't want to talk with me I can't even check mail emails. I can understand this behavior (e.g. lda can't deliver email because sieve script could put such email in folder available via imapc) but it looks like a kind of DoS for my mailbox;) Maybe some kind of switch could be implemented: treat imapc errors as critical or not? Just an idea. Thanks, Marcin
