[Dovecot] proxy (director) and destination ports
by Oliver Eales 26 Nov '10

26 Nov '10

Hello, i am delivering Mail from postfix via LMTP to dovecot. I am using the director also for LMTP. As long as i connect to the dovecot LMTP TCP socket from postfix everything is working. postfix main.cf: virtual_transport= lmtp:localhost:30025 But when i try to switch to the local socket postfix main.cf: virtual_transport = lmtp:unix:private/dovecot-lmtp The dovecot proxy tries to connect to the backend server port 0 which is obviously not working. The proxy always seems to connect to the same port on the backend as it was accessed itself. Nov 24 14:55:09 auth: Debug: master out: PASS 1 user=1000000000030 proxy Nov 24 14:55:09 lmtp(7330): Debug: auth input: user=1000000000030 proxy host=10.1.1.151 proxy_refresh=450 Nov 24 14:55:09 lmtp(7330): Error: lmtp client: connect(10.1.1.151, 0) failed: Connection refused Nov 24 14:55:11 director: Error: director(15.189.34.59:13459/out): connect() failed: Connection refused Is it possible to set the destination port (30025) of the backend server to the proxy ? Regards, Oliver

[Dovecot] Director and deliver
by Thomas Hummel 26 Nov '10

26 Nov '10

Hello Timo, Although I haven't tried neither director nor deliver, I'm planning to try both. I've been catching up with threads on this list talking about director but I'm not sure about how deliver would fit into a setup using director. Since deliver would touch indexes and dovecot-uidlist, wouldn't it need to be proxied as well through director ? Is that the case ? If not, how can we use deliver as LDA in a setup where n directors would proxy to m dovecot backends ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] maildir maintenance?
by Brian Kroth 26 Nov '10

26 Nov '10

Hi, I'm running version 1.2.15 (so no doveadm) with around 6000 maildir users, some of which are very large. For completeness, the details of the setup are as follows: - The maildirs are stored via NFS. - The indexes are on a volume local to the dovecot server. - Only one IMAP server currently. - A separate sendmail/procmail server delivers via NFS. I recently wrote the attached script (could probably be improved) meant in theory to be run as a nightly cron job to do the follow: 1) Remove old messages marked as deleted. (I didn't really like the expunge/trash plugins the last time I looked at them.) 2) Rebuild the indexes to account of those changes. (So that the users aren't delayed by dovecot rebuilding them.) 3) Rebuild FTS indexes. (Again to avoid delay.) 4) Rebuild the maildirsize file. (It seems to become slightly inaccurate over time.) To the devs, I'm wondering if this seems sane? To other users of dovecot, I'm wondering what, if any sort of maintenance operations you tend to do in your setups? Thanks, Brian

[Dovecot] Quota by max file size
by Antonio Perez-Aranda 26 Nov '10

26 Nov '10

Is It possible have a quota for max file size? Per example, If the client try to save a very big mail as draft, p.e. 100M, and the limit of Exim configuration is 20M, the mail is really saved in Maildir at sent or Draft but it can't be sent. I think maybe is easy to create a plugin, get the saved stream size and then if it is over quota max file size, abort save and notice to use about the limit, but at first I want to know that really daesn't similar exists.

[Dovecot] iPhone leaves imap process active
by Jim 26 Nov '10

26 Nov '10

A quick search of the archives didn't reveal a fix, so I thought I'd ask the list. I was running Dovecot 2.0.2, and noticed a lot of CPU being used up. I discovered a number of IMAP processes burning a lot of cycles, when no connections should have been active. I traced this to the iPhone leaving the IMAP connection apparently active. I just upgraded to Dovecot 2.0.7, and I'm still seeing connections left active, but haven't seen the high CPU usage yet, but I've only been running 2.0.7 for about 30 minutes. I tried adding kill_idle to the IMAP config, but that doesn't seem to have helped. Turning off the iPhone does kill the connection, so I know that the iPhone is really keeping the connection alive, but if I can find a way to keep these connections down, I'd really rather have that ability. Here's my config: wrights-Mac-mini:/Users/transmit wright$ doveconf -n # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: Darwin 10.4.0 i386 hfs auth_mechanisms = plain login cram-md5 default_internal_user = _dovecot disable_plaintext_auth = no first_valid_gid = 27 first_valid_uid = 27 last_valid_gid = 27 last_valid_uid = 27 mail_gid = 27 mail_location = maildir:/var/mail/vhosts/%d/%n mail_privileged_group = postfix mail_uid = 27 namespace { inbox = yes location = prefix = type = private } passdb { args = /usr/local/etc/dovecot-mysql.conf driver = sql } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { process_limit = 64 } service imap { idle_kill = 150 secs process_limit = 128 } service pop3-login { process_limit = 64 } service pop3 { process_limit = 128 } ssl = no userdb { args = /usr/local/etc/dovecot-mysql.conf driver = sql } protocol lda { postmaster_address = postmaster(a)example.com } wrights-Mac-mini:/Users/transmit wright$

[Dovecot] auth_username_chars - special chars
by Hajo Locke 25 Nov '10

25 Nov '10

Hello, i use dovecot 1.2.11 with auth by mysql. auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@üÜöÖäÄ for some reasons more special chars in username are needed. in fact the % char is meant. Is this recommend to use with mysql? should i expect some problems when using chars with special function within mysql? Config is now: auth default { mechanisms = plain login passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb prefetch { } } password_query = SELECT `inbox` as `user`, `password`, `home` as userdb_home, `uid` AS userdb_uid, `gid` AS userdb_gid FROM `mail_users` WHERE `login` = '%u' AND `active`='Y' Thanks for your ideas, Hajo

[Dovecot] dovecot transport with postfix and recipient restrictions.
by Mauro 25 Nov '10

25 Nov '10

I'm using dovecot deliver with my postfix smtp. In postfix configuration I have: smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/maps/recipient_checks and in recipient_checks I have: mail(a)example.com REJECT. It doesn't work. Perhaps the recipient restriction has to be put in dovecot side? How can I do this.

That should be the From: field. Depending on what Sieve you use the Subject: should be different. But anyway.. looking at the current Pigeonhole code, it doesn't look like it uses LDA's rejection_subject or rejection_reason settings at all. Stephan, can you add support for those? Or is there a reason why you can't use mail_send_rejection()? Maybe those APIs could be changed to avoid all of this code duplication.. Versions: -dovecot-1.1.7-0_84.el5 -dovecot-sieve-1.1.5-8.el5 The rule I am using is: require ["reject"]; if anyof (address :is "from" "nagios(a)domain1.com") { redirect "newaddress(a)domain2.com"; } elsif anyof (not address :is "from" "nagios(a)domain1.com") { reject text: Hello world. bye . ; } subject label does not work: :subject "This is the new subject"
