[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.

I have created the filter and it works correctly, but reject comes with the following subject: "Mail Delivery Subsystem" How I can do? You didn't mention what Dovecot version. 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"

[Dovecot] Automatic expire on post-login
by Antonio Perez-Aranda 25 Nov '10

25 Nov '10

I need to clear two folder from Maildir at login. Exatly, delete all mails older than 30 days on Trash and 1 day on spam folder. I'm using dovecot 2.0 and I think about use a post-login script calling doveadm -u $user expunge but post-login scripts in dovecot 2.0 are very complex Is there possible to get the environment vars like on dovecot 1.2 ? I think this action must be done by expire plugin, but it isn't the work method if as I understand after read wiki2.dovecot.org about expire plugin, It run only with a cronjob.

[Dovecot] doveadm purge output
by Daniel L. Miller 24 Nov '10

24 Nov '10

Running "doveadm purge" with both -D and -v parms, and both -A and -u options, I don't see much in the way of output. doveadm -v purge -u username just returns with no output doveadm -v purge -A returns no output for most users - for my own mailbox it yields "20 / 21" -D returns the same, along with messages about skipping plugin modules. Is this normal? I'm thinking not - since after deleting messages in the client, emptying the trash, compacting from the client, and then performing a purge - I see no difference in mailbox files. -- Daniel

Re: [Dovecot] zlib + mdbox
by interfaSys sàrl 24 Nov '10

I am. The only issue I'm seeing is Blackberry devices that can't idle after a while. It was the same with Maildir, so maybe it's a zlib issue or something else all together. > > Message: 2 > Date: Tue, 23 Nov 2010 18:19:18 -0800 > From: "Daniel L.
