[Dovecot] Kerberos Cross-Real username
by Nikolay Shopik 16 Dec '09

16 Dec '09

Hi List, Is anyone is running Dovecot with Kerberos and tried to authenticate user from different REALM and have same user principal with default domain. Currently Dovecot only logs user principal w/o REALM. So before I go in production maybe somebody already run into this using Dovecot? If not I just create virtual machines and see how it behaves.

[Dovecot] Auth Fails, But Can Still Get Mail
by Asai 15 Dec '09

Greetings, I've recently upgraded from version .97 to v. 1.2. Everything seems to be working OK, but I'm wondering why I'm getting authentication failure messages in /var/log/maillog. Like this: Dec 15 11:02:41 triata dovecot: imap-login: Disconnected (auth failed, 1 attempts): user=<mycenay>, method=PLAIN, rip=140.9.5.1, lip=140.9.5.1, secured Although that user can log in to the server and get email no problem.

[Dovecot] mail_max_userip_connections
by Richard Stockton 15 Dec '09

15 Dec '09

What is the appropriate setting for mail_max_userip_connections ? My POP3 connections seem to be mostly 1 at a time, but my IMAP connections are often 3 per user per IP. Is this appropriate? If I change the IMAP setting to mail_max_userip_connections=1 will it break things for the user? I am trying to improve this situation: > ps auxwww | grep "imap " | wc 237 3080 22400 TIA, - Richard

by Алексей Крикун 15 Dec '09

15 Dec '09

Hi, I have a question about redirecting message to a multiple addresses. I have an user script like following: require ["copy"]; redirect :copy "addr1(a)dom.ain"; redirect :copy "addr2(a)dom.ain"; All works fine, but if addr1@... has exceeded quota, this script seems stop working and addr2@... doesn't receive this message too. Is this correct behaviour? How to avoid this? Thanks, Kryol

[Dovecot] Dovecot truncating Inboxes?
by Harald Strack 15 Dec '09

15 Dec '09

Hi, Environment: >10000 Users (LDAP) Solaris 10 / sparc imap: dovecot-1.1.10 (pam-unix, no direct LDAP access) pop: dovecot-1.0.14 on another server (pam-unix, no direct LDAP access) mta: postfix (pam-unix, no direct LDAP access) procmail (pam-unix, no direct LDAP access) Filesystems: Inboxes and IMAP-home are on two different SAM-FS volumes. Problem description: Inboxes of users are disappearing / are truncated. we are using dovecot-1.1.0 since two month as main IMAP server. It replaced our long running but old version of UW-IMAP. Till the last week we had no problems and it worked quite well and the whole mail system worked in this configuration since several years. But since a week we receive more and more complaints regarding truncated/deleted mailboxes. First, we assumed user/client errors, but as such messages arrive more frequently, we did a deep analysis of the issue. The only common component of our mail system (postfix (local), procmail, pop, imap) that all concerned users have accessed, was dovecot-imap v. 1.1.10. We have no locking problems, we use fcntl(), dotlock for all mail components. We tested this with a small perl script and locking works fine (no delivery to a locked mailbox and so on...) Finally, all indications point to a bug in dovecot. Google and searches in this mailing list did not come up with any valuable results. Are there any known bugs / configuration problems concerned to the described problem? I greatly appreciate any help! Thx in advance Harald Strack

[Dovecot] Configure deliver to add ', S=<size>' to maildir message name
by alhashash-lists＠cilantrocafe.net 15 Dec '09

15 Dec '09

Hi, I want to use the zlib plugin to compress my mail storage. According to the wiki, only messages with size attribute in the message id should by compressed. If I added the size part, dovecot assumes it is a new message. While dovecot undertands the ',S=<size>' attribute (IMAP shows that size), I could not configure deliver to add the size to message name. I'm using dovecot v1.0.13 Regards, M. Alhashash

[Dovecot] Sieve mails with decoded subject
by Johannes Bauer 15 Dec '09

15 Dec '09

Dear all, I accidently posted this message to dovecot-news and want to apologize for any trouble I may have caused. Here it is again to the correct mailing list: Recently I'm getting a ton of porn/viagra/diet/casino spam mails which I tried to filter with sieve: if header :contains "Subject" [ "[SPAM]", "Bett", "Schlafzimmer", "Spielen", "Luder", "abhenmen", "poppen", "Casino", "Bonus", "abnehmen", "Gewinn", "Potenz" ] { addflag "\\seen"; fileinto "Spam"; stop; } Sadly, this didn't work - taking a closer look upon one of the spam mails, it seems the spamming rats have encoded the subject: Subject: =?US-ASCII?B?RW5kbGljaCBtZWhyIGVuZ2FnZW1lbnQgaW0gQmV0dGNoZW4=?= (reads: "Endlich mehr engagement im Bettchen") I'm thinking about filtering all such encoded subjects (as there's no reason to encode them US-ASCII), but suppose it were UTF-8 or something: how can I filter on the actual content, not the encoded subject? Surely someone has solved that problem already? Kind regards, Johannes

[Dovecot] Mail root to root and permissions problem
by Antonello Onida 15 Dec '09

15 Dec '09

Hi all! I got a Debian with postfix-dovecot-spamassassin. I got a non perfect installation: when an internal mail has been sent i got this error: <error> ex: from root@* to root@*. Command output: Can't open log file /var/log/dovecot.log: Permission denied </error> Operations like "dovecot: 2009-12-15 11:17:24 Warning: Killed with signal 15" are writen. It's a permission problem: dovecot.log is owned by "root" and grupped by "adm" (chmodded 640). Where is the problem? I'm really blind now! Tx 4 suggestions! Bye, Antonello

by Zhang Huangbin 15 Dec '09

15 Dec '09

Hi, list. In dovecot-1.2, managesieve is identified as 'sieve' service while use '%s'[1] in dovecot. Is it possible to change it? Because we store it in SQL/LDAP as 'managesieve' service name, we don't want to change this. Thanks [1] http://wiki.dovecot.org/Variables -- Best Regards.
