Dovecot quota
by David Mehler 28 Mar '18

28 Mar '18

Hello, I'm running Dovecot on a FreeBSD system with Postfix in a virtual user setup, with Mysql. I am trying to understand the quota configuration. I've got a Mysql database with an accounts table with a quota field. I've also got two other tables one quota (currently has nothing in it an empty set), and quota2 messages and bytes which has one entry. My goal is to have different quotas for each user so say one user has a 512MB quota I put 512 in the accounts quota column, while another user might have 256MB, put 256 in the accounts quota column. These are just examples. I'm assuming messages in the quota2 table track how many messages are under that user's is it inbox or all folders in the account? And bytes is that the space being taken up again by inbox or by all messages in the account? I'm also trying to have a separate quota for my public folders, which is not working. If anyone could take a look at this configuration see if it looks good and maybe where public is not happening i'd appreciate it. Thanks. Dave.

Released Pigeonhole v0.5.1 for Dovecot v2.3.1.
by Stephan Bosch 28 Mar '18

28 Mar '18

Hello Dovecot users, Here's the Pigeonhole release that goes with Dovecot v2.3.1. You will need this release for Dovecot v2.3.1, because the previous v0.5.0.1 release will not work. Apart from compatibility changes, it only contains bugfixes. Changelog v0.5.1: - Explicitly disallow UTF-8 in localpart in addresses parsed from Sieve script. - editheader extension: Corrected the stream position calculations performed while making the modified message available as a stream. Pigeonhole Sieve crashed in LMTP with an assertion panic when the Sieve editheader extension was used before the message was redirected. Experiments indicate that the problem occurred only with LMTP and that LDA is not affected. - fileinto extension: Fix assert panic occurring when fileinto is used without being listed in the require line, while the copy extension is listed there. This is a very old bug. - imapsieve plugin: Do not assert crash or log an error for messages that disappear concurrently while applying Sieve scripts. This event is now logged as a debug message. - Sieve extprograms plugin: Large output from "execute" command crashed delivery. Fixed buffering issue in code that handles output from the external program. The release is available as follows: https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.1.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.1.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

dovecot logging
by A. Schulze 27 Mar '18

27 Mar '18

Hello, I'm currently playing with a number of dovecot instances to evaluate my "next generation setup" For now I run 6 instances of dovecot, one per docker container: - 2x redirector - 2x backend #1 - 2x backend #2 All docker container use syslog. And there the problems starts. Every instance identify itself as "dovecot" That's not helpful :-/ I tried to set an instance name but that change nothing. My options are now - let rsyslogd separate the sources by IP - use logfiles files Are there other? Currently the code use a fixed string "dovecot": https://github.com/dovecot/core/blob/master/src/lib-master/master-service.c… I would ask if it's possible to use the instance name as syslog identifier, too?

Slow imap connection to local dovecot server
by Lothar Paltins 27 Mar '18

27 Mar '18

Hi, this is my setup: OpenSuse tumbleweed dovecot 2.3.0.1 (ffd8a29) thunderbird 52.6.0 I'm running a local dovecot server on my private network to be able to access my saved mails from several computers on the network. The network is behind a firewall, therefore I'm only using plain imap on port 143 with plain text password authentification. But very often the login from thunderbird to the dovecot server takes a very long time, even if thunderbird and dovecot are running on the same machine. It can take more than a minute until I can read a message. I dont't have this problem with the remote imap servers of my mail providers. Does anybody know, why this happens or how I could debug this issue?

Duplicate mails on pop3 expunge with dsync replication on 2.2.35 (2.2.33.2 works)
by Gerald Galster 27 Mar '18

27 Mar '18

Hello, consider the following setup with dovecot 2.2.35: smtp/587 (subject: test 1535) | | mx2a.example.com --> dsync/ssh --> mx2b.example.com | pop3 fetch/expunge (uid 23) | !! dsync (copy from INBOX -> uid 24) /| dsync (expunge uid 23) / The pop3 client deletes mail from the server which triggers a copy from INBOX before it is expunged. On the next pop3 fetch you get the copy of the mail you thought had been expunged. This occurs only if mail is received by smtp on mx2a, synced to mx2b via dsync/ssh and then expunged via pop3 on mx2b. It does not occur if mail is received and expunged on mx2b. As a temporary workaround the system has been downgraded to 2.2.33.2. There are no duplicate emails after expunge with this version. 2.2.34 has not been tested. Does anyone know if there were changes in the dsync code from 2.2.33.2 to 2.2.35? Log: (mail received on mx2a.example.com and delivered via dsync to mx2b.example.com, then expunged via pop3 on mx2b.example.com -> copy/duplicate) Mar 26 15:35:57 mx2b.example.com dovecot[3825]: pop3-login: Login: user=<poptest(a)example.com>, method=PLAIN, rip=91.0.0.1, lip=188.0.0.1, mpid=3922, TLS, TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) Mar 26 15:35:58 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): expunge: box=INBOX, uid=23, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Mar 26 15:35:58 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): Disconnected: Logged out top=0/0, retr=1/1259, del=1/1, size=1242 Mar 26 15:35:58 mx2b.example.com dovecot[3825]: doveadm: Error: dsync-remote(poptest(a)example.com): Info: copy from INBOX: box=INBOX, uid=24, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Mar 26 15:35:58 mx2b.example.com dovecot[3825]: doveadm: Error: dsync-remote(poptest(a)example.com): Info: expunge: box=INBOX, uid=23, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 (mail received on mx2b.example.com and expunged via pop3 on mx2b.example.com -> no copy/duplicate) Mar 26 15:36:09 mx2b.example.com dovecot[3825]: pop3-login: Login: user=<poptest(a)example.com>, method=PLAIN, rip=91.0.0.1, lip=188.0.0.1, mpid=3927, TLS, TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) Mar 26 15:36:09 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): expunge: box=INBOX, uid=24, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Mar 26 15:36:09 mx2b.example.com dovecot[3825]: pop3(poptest(a)example.com): Disconnected: Logged out top=0/0, retr=1/1259, del=1/1, size=1242 Mar 26 15:36:10 mx2b.example.com dovecot[3825]: doveadm: Error: dsync-remote(poptest(a)example.com): Info: expunge: box=INBOX, uid=24, msgid=<ACD482CD-443E-479A-A9E9-67549E186E35(a)example.com>, size=1210, subject=test 1535 Thanks for looking into this Gerald

Quota set-up problems
by Marcin Norek 26 Mar '18

Hi, I've recently started using Dovecot as our main mail storage, and it's performing great. But I have a question/problems with quotas. First of we are using: dovecot --version 2.2.32 (dfbe293d4) Dovecot is a part of a pre set environment (mailcow-dockerized) Aside the inbox namespace we have set-up an additional archive ns (Archiwum) like this namespace Archiwum { type = private separator = / prefix = Archiwum/ location = maildir:/var/vmail/arch/%n:INDEXPVT=~/Maildir/Archiwum subscriptions = yes list = yes mailbox "Wyslane" { auto = subscribe } } It is on an separate disk array, and works well. The problem is that this namespace and all its sub mailboxes should have different quota then the main storage so the config is like this quota = dict:Userquota::proxy::sqlquota quota2 = maildir:ns=Archiwum quota_rule = Trash:storage=+100% quota2_rule = *:ignore It works.. but not as intender. While mail located directly in the name space are ignored everything in sub mailbox of the Archiwum is still accounted to the main quota. I've been fighting this for some time now and can not find the solution. So help would be appreciated. Regards Marcin

destuser setting useless on LMTP proxy
by Jan-Pieter Cornet 26 Mar '18

I tried setting the "destuser" setting on the LMTP director as follows, to preserve the original envelope rcpt: protocol lmtp { auth_socket_path = director-userdb passdb { driver = ... override_fields = destuser=%{orig_user} } } The passdb driver would return the appropriate "user" for each alias. Suppose, for example, user1 has emails user1(a)domain.tld, but also alias1(a)domain.tld. Now, it turns out that setting the destuser *changes* the backend. It seems that when the passdb returns "destuser", that username is completely ignored and the hashing of the destuser determines the backend chosen. This is incorrect, the backend should be chosen based on the returned "user", and the "destuser" should only be used for the remote login (or rcpt, in case of LMTP). I'm using version 2.2.35. The problem seems to be in lmtp/commands.c, in client_proxy_rcpt_parse_fields, line 281-285 says: } else if (strcmp(key, "user") == 0 || strcmp(key, "destuser") == 0) { /* changing the username */ *address = value; } ... So it looks as if "user" and "destuser" are treated equally in the LMTP proxy. -- Jan-Pieter Cornet <johnpc(a)xs4all.net> Systeembeheer XS4ALL Internet bv www.xs4all.nl
