[Dovecot] lmtp: Error: mmap failed with file ... dovecot.index.cache: Cannot allocate memory
by David Jonas 10 Aug '12

10 Aug '12

Hello, I have a mailbox with an ungodly number of small messages in it. When new messages are delivered lmtp kicks up an error like the one below. I tried raising the vsz_limit for lmtp but that didn't see to help. Any ideas (besides deleting 400k messages)? Thanks! dovecot: lmtp(6068, user(a)example.com) Error: mmap() failed with file /home/vmail/domains/example.com/user/Maildir/dovecot.index.cache: Cannot allocate memory # ls -lah dovecot.index.cache -rw------- 1 vmail vmail 128M Jul 29 20:16 dovecot.index.cache # doveadm mailbox status -u user(a)example.com all inbox INBOX messages=434118 recent=59848 uidnext=434119 uidvalidity=1293568548 unseen=432625 highestmodseq=14023 vsize=1329486283 guid=f8d48232244a1a4dfe2e0000cb0ad7e0 # doveconf -n ... default_vsz_limit = 256 M service lmtp { inet_listener lmtp { port = 24 } vsz_limit = 256 M }

[Dovecot] postfix mysql quota map to dovecot dict in mysql
by Benny Pedersen 10 Aug '12

10 Aug '12

currently dovecot dict is CREATE TABLE IF NOT EXISTS `quota` ( `username` varchar(100) COLLATE latin1_general_ci NOT NULL, `bytes` bigint(20) NOT NULL DEFAULT '0', `messages` int(11) NOT NULL DEFAULT '0', PRIMARY KEY (`username`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci; there is not field that says how much quota each user have, so one cant make a query on how much its left pr user how can i resolve this in dovecot dict ? i like to do an postfix mysql map to temp reject if quota is out of limit -- Benny Pedersen

[Dovecot] Server side Sieve with virtual users
by Luigi Rosa 10 Aug '12

Is there a way to implement server-side filters with Dovecot configured with virtual users (userbase in mysql, a single *NIX user account that owns /var/spool/mail and its content)? Thanks Ciao, luigi -- / +--[Luigi Rosa]-- \ A generation which ignores history has no past... and no future.

This is the hard part. Depending on your preferred distro here are two nice webpages for this: http://wiki.mediatemple.net/w/(ve):Install_Postfix_with_Dovecot_on_CentOS http://workaround.org/ispmail Second step is to enable sieve, for witch you only need to uncomment the specific lines from dovecot.conf. For dovecot 1.2, you will have something like: protocols = pop3 pop3s imap imaps managesieve protocol lda { ... mail_plugins: quota sieve } protocol managesieve { } plugin { ... sieve=~/.dovecot.sieve sieve_dir=~/sieve } -- Best regards, Adrian Minta

[Dovecot] Dovecot LMTP - Delivered-To header weirdness
by Daniel Piddock 09 Aug '12

09 Aug '12

Hi, I'm not sure if this is a deliberate design decision or a technical limitation that I've missed. Please briefly explain if so :). Or a bug or feature request? When LMTP receives a mail with a single recipient it adds a Delivered-To header. However if the message is delivered in a batch that header isn't added. At first I thought maybe the LMTP was doing something with hardlinks but that doesn't appear to be the case (for rather obvious reasons.) Sample headers (single recipient): Return-Path: <user(a)domain.test> Delivered-To: <user(a)domain.test> Received: from mx.domain.test ([127.0.0.1]) by domain.test (Dovecot) with LMTP id ZNTPFX2NI1CcCwAAVMeomg for <user(a)domain.test>; Thu, 09 Aug 2012 11:14:21 +0100 Envelope-to: user(a)domain.test Delivery-date: Thu, 09 Aug 2012 11:14:21 +0100 Received: from host.domain.test ([172.16.252.1]:44058) by relay.domain.test ([172.16.252.120]:25) with esmtp id 1SzPkz-0000lz-7v (Exim 4.80) for user(a)domain.test (return-path <user(a)domain.test>); Thu, 09 Aug 2012 11:14:21 +0100 Message-ID: <50238D7D.2000707(a)domain.test> Date: Thu, 09 Aug 2012 11:14:21 +0100 From: User <user(a)domain.test> To: User <user(a)domain.test> Subject: test And an expansion list: Return-Path: <user(a)domain.test> Received: from mx.domain.test ([127.0.0.1]) by domain.test (Dovecot) with LMTP id Gf+yBmiNI1CECwAAVMeomg ; Thu, 09 Aug 2012 11:14:00 +0100 Envelope-to: expansion(a)domain.test Delivery-date: Thu, 09 Aug 2012 11:14:00 +0100 Received: from host.domain.test ([172.16.252.1]:44053) by relay.domain.test ([172.16.252.120]:25) with esmtp id 1SzPkd-0000ls-Qr (Exim 4.80) for expansion(a)domain.test (return-path <user(a)domain.test>); Thu, 09 Aug 2012 11:13:59 +0100 Message-ID: <50238D67.3090802(a)domain.test> Date: Thu, 09 Aug 2012 11:13:59 +0100 From: User <user(a)domain.test> To: Expansion <expansion(a)domain.test> Subject: test At the moment we've turned off batch delivery in the exim smtp transport (max_rcpt=1).

[Dovecot] dovecot+LDAP/AD encoding issue
by Wiethoff, Helge 09 Aug '12

09 Aug '12

Hello everybody, i have a problem with dovecot+Active Directory as Authentication-Service. I am not able to use special characters (äöüß (german umlaut)) within a password. Normally I would suggest that the ldap-query is done in UTF-8 but as I debugged the auth-process, I have seen that the password is ISO-8859-1 encoded. The "original" query (from roundcube for example) is UTF-8 encoded (I dumped the POST-Query). So far I wasn't able to find my error by myself or by searching the web. Maybe someone of you can give me a hint :-) Thanks and greetings from Germany, Helge ---- dovecot --version 2.0.16 ---- D-AS01:/etc/dovecot # grep -v '^ *$#.*$\?$' dovecot-ldap.conf.ext uris = ldap://10.37.5.90 dn = CN=ldap-d-as01,CN=Users,DC=tfh-bochum,DC=de dnpass = xxxx auth_bind = yes ldap_version = 3 base = ou=Benutzer, ou=Lehre, dc=tfh-bochum, dc=de user_attrs = =uid=10000,=gid=10000,=home=/srv/mail/%Ld/%Ln user_filter = mail=%u pass_attrs = =uid=10000,=gid=10000,=home=/srv/mail/%Ld/%Ln pass_filter = (&(mail=%u)(!(extensionAttribute3=*))) ---- dovecot -n # 2.0.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37.6-0.11-default x86_64 openSUSE 11.4 (x86_64) auth_debug = yes auth_mechanisms = plain login auth_username_translation = %Lu auth_verbose = yes mail_location = maildir:~/Maildir mail_max_userip_connections = 1000 mail_plugins = quota managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { inbox = yes list = yes location = prefix = INBOX/ separator = / subscriptions = yes type = private } namespace { list = yes location = maildir:%%h/Maildir:INDEX=%h/Maildir/shared/%%u:CONTROL=%h/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = yes type = shared } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/srv/mail/shared-mailboxes quota = maildir:Quota quota_rule = *:storage=1G sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 10 } protocols = imap pop3 sieve lmtp service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0770 user = root } } service imap-login { process_min_avail = 4 service_count = 0 } service managesieve-login { inet_listener sieve { address = * port = 4190 } inet_listener sieve_deprecated { address = * port = 2000 } process_min_avail = 2 service_count = 0 } ssl_ca = </etc/ssl/certs/tfh_dfn_dtag_cacert.pem ssl_cert = </etc/ssl/certs/imap.stud.tfh-bochum.de-20110530-cert-302177588.pem ssl_key = </etc/ssl/private/imap.stud.tfh-bochum.de-20110530.key userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota } protocol imap { mail_plugins = quota acl imap_acl imap_quota } protocol pop3 { mail_plugins = quota } ________________________________ Helge Wiethoff Medienzentrum Telefon: +49 (234) 968 8717 Fax: +49 (234) 968 3453 E-Mail: Wiethoff(a)tfh-bochum.de Technische Fachhochschule Georg Agricola für Rohstoff, Energie und Umwelt zu Bochum Staatlich anerkannte Fachhochschule der DMT-Gesellschaft für Lehre und Bildung mbH Herner Straße 45 44787 Bochum http://www.tfh-bochum.de ________________________________ Träger: DMT-Gesellschaft für Lehre und Bildung mbH Sitz der Gesellschaft: Bochum Registergericht: Amtsgericht Bochum Handelsregister: B 4052 Geschäftsführung: Prof. Dr. Jürgen Kretschmann (Vorsitzender) Manfred Freitag

So there is an imap expunge entry for all of the mails that get lost? You should be able to match that with the IMAP client's IP address by using session IDs, for example: mail_log_prefix = "%s(%u) <%{session}>: " Also you may be able to find out what client is doing it by setting: imap_id_log = *

[Dovecot] Mail deletion and Solr index update
by Matthias Rieber 09 Aug '12

09 Aug '12

Hi, I've deleted 10000s emails and it seems that every mail is removed with a single request from Solrs index. This works, but it's quite slow. Is it possible/plans to improve that? Matthias
