[Dovecot] Question about SASL auth
by Mark Sapiro 03 Apr '10

03 Apr '10

I have recently upgraded from Dovecot 1.2.10 to 2.0.beta3. I have Postfix 2.3.3 and use Dovecot to provide SASL auth for Postfix. # dovecot -n # 2.0.beta3: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.18-8.1.14.el5 i686 CentOS release 5 (Final) auth_mechanisms = plain apop login auth_worker_max_count = 5 mail_location = mbox:~/Mail:INBOX=/var/spool/mail/%u mail_privileged_group = mail mbox_write_locks = fcntl dotlock passdb { args = /usr/local/etc/dovecot.passwd deny = no driver = passwd-file master = no pass = no } passdb { deny = no driver = pam master = no pass = no } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </etc/postfix/sbh16-cert.pem ssl_key = </etc/postfix/sbh16-key.pem userdb { driver = passwd } Since upgrading to 2.0.beta3 I have started seeing notices like Mar 6 07:06:20 sbh16 postfix/smtpd[30273]: warning: SASL: Connect to private/auth failed: Resource temporarily unavailable Mar 6 07:06:20 sbh16 postfix/smtpd[30273]: fatal: no SASL authentication mechanisms in my maillog. I don't see them too often (an average of about 2 occurences per day), and they seem to be related to spam or some kind of attack. I am able to send using SASL authentication from my own client OK. The relevant postfix config settings are smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot Postfix and its configuration haven't changed from what I used with Dovecot 1.2.10. With Dovecot 1.2.10, I rarely if ever saw these failures. Is this a case of the socket being in use when another auth request arrives or is it something else? And if it is the socket in use, is there some change in 2.0.beta that would cause the socket to be busy longer? -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] simple steps with sieve
by Gavin Hamill 03 Apr '10

03 Apr '10

Today is my first day with sieve, so be gentle :) I'm trying to set up a pretty webmail interface to our Dovecot 1.2.4 server using roundcube. The managesieve config + roundcube 'managesieve' plugin work fine, and I'm able to use roundcube's UI to generate .dovecot.sieve files. We use winbind + LDAP lookups to do some exotic mail rewriting... ultimately user.name(a)domain.com gets rewritten to 'ar-cloh@localhost', and in /home/AD/ar-cloh/.dovecot.sieve there is only this: require ["vacation"]; # rule:[gdh_test] if anyof (header :contains "Subject" "test") { vacation "test away"; } When I send an email to the user, I see this in the mail.log Oct 19 15:39:43 ar-smtp-1 dovecot: deliver(ar-cloh): sieve: msgid=<1255963176.14420.31.camel@gdh-work>: discarding vacation response for message implicitly delivered to <ar-cloh@ar-smtp-1> I don't understand; sending a vacation for implicitly-delivered messages sounds exactly like what I want - is there any way to say 'do this anyway' ? gdh

[Dovecot] Any info about 1.2->2.0 migration ?
by Michal Hlavinka 02 Apr '10

02 Apr '10

Hi, there are few documents on the wiki ( http://wiki.dovecot.org/Upgrading ) about migration between old versions. Is there any document for 1.2->2.0 or list of configuration changes (especially the missing ones) in 2.0? Regards, Michal Hlavinka

[Dovecot] IMAP extensions & their meanings
by Jerry 01 Apr '10

01 Apr '10

I know that is is not really a Dovecot problem; however, I was wondering where I could get a complete list of the terms used in the 'capability' line. I have not had any success in finding out what things like "XLIST" refer to. I don't believe that is one that Dovecot uses; however, I have seen it with other IMAP servers, plus lots of other flags that I do not understand. I tried Googling but only got a few sporadic and basically useless answers. Thanks! -- Jerry Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.
