[Dovecot] Running spamc during LMTP delivery
by martin f krafft 12 Aug '12

12 Aug '12

Hello list, we are using dovecot-lmtp for delivery to virtual users, and vmm[1] to manage them. 1. http://vmm.localdomain.org/ One nice feature of vmm is that every virtual user has their own UID/GID on the UNIX filesystem. There is no passwd entry, so no shell login, but each user effectively has a home directory and can run commands in isolation and with lowered privileges. This requires dovecot-lmtp because only the LMTP LDA runs with root rights and can drop privileges to become the specific user for which it is delivering mail. We would now like to run SpamAssassin with the possibility of using the antispam plugin to enable virtual users to train their databases. Do you have an idea how I could let dovecot-lmtp invoke spamc? Or an external command as a filter, to be run by the final user? Thanks, -- martin | http://madduck.net/ | http://two.sentenc.es/ "truth is stranger than fiction, but it is because fiction is obliged to stick to possibilities; truth isnt." -- mark twain spamtraps: madduck.bogus(a)madduck.net

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.

[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

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.

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.

[Dovecot] Quota dict configuration

Hi, I have enabled quota dict with mysql following wiki http://wiki2.dovecot.org/Quota/Dict Everything work as expected. I just have a question about query used for updating quota usage. I already check the source file dict-sql.c but i still can't figure it out. I store user info in a mysql table where only left (user) part of an email address is stored with foreign id for domain conected to domain table. The problem is administration because quota table have primary key whole email. Is there even possible to configure quota dict settings to use separate variables %n and %d like in user and password query? -- lp Uroš

[Dovecot] dsync and pop3 migration plugin fails for large inbox due to idle timeout
by Nikolai Schupbach 08 Aug '12

08 Aug '12

Timo, There is a problem with the dsync POP3 migration plugin when syncing a large INBOX. What happens is dsync establishes a connection to the POP3 server at the beginning of the sync, but then it sits there idle until it's used to sync the UIDLs. On a very large inbox with many thousands of messages it will be idle for longer than a POP3 server's idle timeout setting. When the UIDL sync occurs dsync produces the following errors (because the connection has been lost due to the POP3 server's inactivity timeout): dsync(first.last(a)test.co.nz): Error: pop3c(pop3.test.com): Server disconnected unexpectedly dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 13: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 15: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 16: Disconnected ... dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14492: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14493: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14494: Disconnected Also at the end of the dsync it actually has an exit status of 0, but it shouldn't because the POP3 sync failed, and none of the UIDLs are retained. Dsync should try to keep the POP3 connection alive, by sending a regular 'NOOP' command to the POP3 server, or it should simply reconnect if sees the connection is lost. At the moment the only work around is to increase the POP3 server's idle timeout to a multi hour value, which isn't a good work around as it causes a lot of inactive POP sessions to bank up. Regards, Nikolai.

[Dovecot] doveadm import is always verbose

And using the option -v with: doveadm -v import -u guser mbox:/tmp/mbox/guser/restore_2012-05-08 restore_2012-05-08 all makes no difference at all, the same messages appear.

[Dovecot] Dovecot with Company - level Quota
by Kavish Karkera 08 Aug '12

08 Aug '12

Hi Timo, We are using maildir as quota-backend , and performing user level quota, which is working fine. (using dovecot 2.x ). Now the requirement is to , restrict the quota to client / company level along with user level quota. For. eg. We have a mailbox path like /mail/mailstore/10001/kavish.karkera(a)linoquery.com/Maildir/ where 10001 is Client code (unique number given to very client) instead of domain name. So there would be two quota's one at company level and other user level. Such as 10001(linoquery.com) = 5GB ---> Company Quota kavish.karkera(a)linoquery.com = 0 ? ---> User Quota If the sum of the user quota under 10001/* exceeds the 5GB limit then the mails for that particular domain should get bounced. Please Help , if this is possible. Regards, Kavish Karkera

good day! I wonder if it is possible to make a chain of replication in dovecot 2.1.9. Now I'm using two way replication(I use proxy to redirect users) and it's working just fine but is it possible to setup replication like this: serverA ---> serverB --> server C <--- I've added additional mail_replica2 on serverB and after restart dovecot didn't complain about errors, with doveconf -n I am able to see two replica's settings but user's mails aren't replicating to server C. no errors in logs. I want to use server C as backup server with lvm snapshots.

Do the same user(s) have this problem and/or do each user have their own mail configuration for their mail readers? If yes, I would also check that the port and security protocol matches (i.e. clear/TLS/SSL on ports 110/110/995 respectively). Mismatched configurations could cause what you describe. Log messages could also be helpful here. Joseph Tam <jtam.home(a)gmail.com>

Re: [Dovecot] redirect actions exceeds policy limit

Thank you David, I saw that in the share/docs but we didn't have the /conf.d/ folder or any of the extra conf files in place. I created that directory, copied the file over, made my changes and all is well again. Not sure why things were setup the way they were, after looking at the other files in conf.d it would appear the previous sysadmin had merged a lot of those bits and pieces into the main dovecot.conf file. Perhaps leftovers from v1.x days. Will likely address that down the road when we update that server. Mike Greene Rock Island Technology Solutions, Inc.
