[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.

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
