[Dovecot] selective disable_plaintext_auth
by Mariano Absatz 11 Nov '09

11 Nov '09

Hi, I've been using dovecot for some time now, always with the setting: disable_plaintext_auth = yes so that no user can accidentally expose their username/password in the open. However, I'm now trying to configure a webmail client in a nearby server which doesn't support TLS or SSL IMAP connections :-( Is there any way to allow plaintext_auth only for a small set of IP addresses (for what I see in the comment, this is automatic for local addresses, alas, the webmail client is on another host).

by Shane Arnold 11 Nov '09

11 Nov '09

Hi All, Sorry if this is a dumb questions, but what methods are available for retrieving mail for a system user i.e www-data. Basically my setup is just a normal Dovecot-IMAP which is working fine for shell users, but I want to be able to read mail for system users via IMAP. Is this doable? Cheers

[Dovecot] Multiple instances of dovecot in the same machine.
by Rodolfo Gonzalez Gonzalez 10 Nov '09

10 Nov '09

Hello all, I'm trying to run several instances of dovecot, with a different config each one, following the instructions from here: http://wiki.dovecot.org/RunningDovecot I try the command dovecot -c /etc/dovecot/installN/dovecot.conf and get: --- Error: ssl_cert_file: Can't use /etc/ssl/certs/dovecot.pem: No such file or directory Fatal: Invalid configuration in /etc/dovecot/installN --- but in my /etc/dovecot/installN/dovecot.conf file I have these lines: ssl_cert_file = /etc/dovecot/installN/ssl/certs/dovecot.pem ssl_key_file = /etc/dovecot/installN/ssl/private/dovecot.pem where both files exist and are valid. Any help is appreciated. Thanks, Rodolfo.

[Dovecot] [Fwd: Re: Bug in BODYSTRUCTURE]

Fyi... Sam Varshavik (courier-imap developer) claims (on the courier-imap list, see attached) dovecot is incorrectly parsing messages with missing/invalid "MIME-Version:" header... I have no clue if he is correct... if so, maybe this has already been fixed?

[Dovecot] Missing 'mailbox' variable ?
by David Goncalves 10 Nov '09

10 Nov '09

Hi, I'm using Dovecot with LDAP. My users have an home directory and a field named 'mailMessageStore'. Then the full mailbox path is 'homeDirectory/mailMessageStore' In dovecot-ldap.conf i configured as follows : user_filter = (&(objectClass=qmailUser)(cn=%u)) user_attrs = qmailUID=uid,qmailGID=gid,homeDirectory=home,mailMessageStore=mail=maildir:~/%$ Everything is working as expected but... I'm using sieve and in the 'dovecot.conf' there is no way to get a variable containing the mailbox path... As the mailMessageStore field can contain something different than the login or uid, how can i get the mailbox path in the conf ? Regards. -- David Goncalves - http://www.lestat.st

[Dovecot] Auth failure delays
by Timo Sirainen 09 Nov '09

09 Nov '09

Currently Dovecot works like this when authentication fails: - the delay is always at least auth_failure_delay seconds (default: 2s) - each failed attempt doubles the delay for that specific imap/pop3 connection (no such delays for e.g. smtp) - the delay's upper limit is 3 minutes For v2.0 I was planning on making dovecot-auth process do these checks and keeping the state in anvil process: - the delay is always at least auth_failure_delay seconds (default: 2s) - for each remote IP address the delay is doubled, regardless of how the request comes (imap, pop3, smtp, etc). - the delay's upper limit is .. hardcoded to 15 secs? i kind of hate the thought of making this configurable. - each successful authentication from the IP resets the IP's delay - the delay happens before authentication is even attempted, so even successful auth attempts will have the delay (unless of course there haven't been auth failures from that IP) If the upper limit is 15 secs, that means max. 240 auth attempts per hour per IP. The reason I was thinking 15 secs is because I have some vague memories about Thunderbird dropping connection after 15 or maybe 30 seconds of idling. If user has one successful login, it's of course possible to get around the delay doubling by just doing failed attempt -> successful attempt -> failed -> success -> etc. But probably no one is really going to try to do that, and even if they did it's still not that bad. The second successful login will still have that 2 second delay before it resets the delay. So that's still max one auth/2 seconds or max. 1800 auth attempts/hour. Any thoughts?
