[Dovecot] MySQL as a storage only.?
by Romer Ventura 24 Dec '08

24 Dec '08

Hello, I was wondering is I could use MySQL as storage only..? Meaning that no user information, other than the obvious email address associated with an specific email so that each email can be showed to the right user, will be stored in a MySQL database instead of /home/vmail/DOMAIN/<user> Would I get any advantages.? Would it be better, faster? Thanks

by Volker Siebelink 23 Dec '08

23 Dec '08

Hello, I set up Dovecot so that I now have about 20 domains on my mailserver. So far everything works fine. Now I have the need to set up shared maildirs, but they shall only be shared for the users of just one domain. What do I have to do? Thanks in advance for any hint! Volker

[Dovecot] Is there a straight forward way to associate login with imap process
by Jack Stewart 23 Dec '08

23 Dec '08

Hi, Is there a way to associate a user's the login (imap-login) process with the user's 'imap [' process? We are trying to lock down an issue to make sure we full understand it. /proc and shared memory tools weren't particular useful. Just for context, we are having an intermittent locking index cache locking issue that appears to impact only a subset of our users. The index files are on NFS. It may be fixed by a dovecot patch (we are at 1.1.3), adjusting our tcp_timeout on the servers, upgrading out circa 2000 load balancer, the type and configuration of the multiple simultaneous persistent clients that user is using, etc. lslk, alert logs, strace, testing the most recent 1.1.X version, and file mtime is giving us some information but we want to make everything is covered. Many thanks in advance. ---Jack -- Jack Stewart California Institute of Technology jstewart(a)caltech.edu / www.imss.caltech.edu

[Dovecot] POP3 Immediate Connection Termination
by Kat Wisnosky 23 Dec '08

23 Dec '08

Hey everyone... Thanks in advance for any help. I seem to have the opposite problem that a lot of people have - I've been running Dovecot v. 1.0.10 quite successfully for IMAP for several months. However, one of our executives has her heart set on being able to get her mail via POP3. It looks to me like I have both configured, but when trying to log in via a POP3 or POP3s connection either via a client or through telnet, the connection is created than immediately terminated.

[Dovecot] Move mail in Maildir without IMAP
by RW 21 Dec '08

21 Dec '08

I set-up some spam/ham learning folders where a crontab entry learns the mail and them moves it do a different Maildir folder. Unfortunately, since it has a different dovecot-keywords file, any imap flags get changed to unknown-0, unknown-1 etc. I tried the following, but it didn't work mv "${src_ham}"/cur/* "$dest_ham"/new/ cp "${src_ham}"/dovecot-keywords "${dest_ham}" Is there a simple way to do this correctly without going through IMAP? And are there any more serious consequences of moving mail like this, with dovecot imap running on top.

[Dovecot] Dovecot with LDAP on multiple domains ?
by Guillaume Hilt 20 Dec '08

20 Dec '08

Hello, I intend to set up a mail server for a few domains with Dovecot/Postfix/MySQL/DSPAM and antispam plugin. The better solution to manage users would be to set up a ldap server. So, do anyone have ever set up this kind of server with dovecot ? Any advice that would help me ? Thanks, -- Guillaume Hilt

[Dovecot] More info from mail_log plugin
by Bardur Haskor 19 Dec '08

19 Dec '08

HiWe need to track exactly when our users read messages. Unfortunately, I haven't been able to figure out how we can achieve this with Dovecot. Then I saw the mail_log plugin.Is it possible to extend the plugin to also log system flag changes? This would be great, because then we could see in the log files when the Seen flag has been set. Changes in user defined flags would also be interesting to track.I know this would create a lot of log entries, but for us this wouldn't be a problem. Maybe the plugin would default to not tracking flag changes, but could be configured to do so.RegardsBardur Ha Skor _________________________________________________________________ Connect to the next generation of MSN Messenger http://imagine-msn.com/messenger/launch80/default.aspx?locale=en-us&source=…

[Dovecot] "nopassword" extra field useless with LDAP passdb
by Zohan 19 Dec '08

19 Dec '08

Hi, We are trying to implement a highly secure mail server with user authentication restricted to SSL certificates only (not using passwords at all). Still, user information is stored in a LDAP directory. In this configuration LDAP is used to check whether the user is registered (and probably supply quota and other info), and actual authentication is done by SSL layer. According to wiki, a "nopassword" extra field should be supplied, together with empty password. But there is no way to return an empty password from LDAP, as LDAP simply does not allow "empty attributes"; if an attribute is present, it is not empty. Supplying empty password as a static field (like this: pass_attrs = uid=user,=password=,nopassword) works an odd way, allowing empty password only, not "any password", and most MUAs (including our target Thunderbird) do not allow empty passwords. Log excerpt follows ("1" was entered as a password during POP3 session; static empty password was configured as above): ==================== Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): pass search: base=ou=People,dc=example,dc=com scope=subtree filter=(&(objectClass=inetOrgPerson)(uid=user1)) fields=uid,nopassword Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): result: uid(user)=user1 Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): Password mismatch Dec 9 02:11:15 localhost dovecot: auth(default): ldap(user1,127.0.0.1): PLAIN(1) != '' Dec 9 02:11:17 localhost dovecot: auth(default): client out: FAIL 1 user=user1 Dec 9 02:11:19 localhost dovecot: pop3-login: Aborted login (auth failed, 1 attempts): user=<user1>, method=PLAIN, rip=127 .0.0.1, lip=127.0.0.1, secured ==================== That's why we now have to maintain a separate passwd-like file with the following contents: user1:::::::nopassword user2:::::::nopassword ... and so on (updating it each time manually as users are added/removed), and use it as passdb. Only this allows true "any password" policy. In fact, the problem seems to be a little bit deeper. In our setup user/password challenge is not needed at all. This is exactly what RFC 4959, "IMAP Extension for Simple Authentication and Security Layer (SASL) Initial Client Response", is about (http://tools.ietf.org/html/rfc4959 , see SASL EXTERNAL example). Are there any plans to implement SASL EXTERNAL mechanism in Dovecot? Thank you! Zohan

[Dovecot] OT: Looking for a robust IMAP client
by Stewart Dean 19 Dec '08

19 Dec '08

This weekend we had a runaway email endless loop. When it was killed after 18 hours, my inbox had 135,000 messages in it...there were two messages that were being endlessly sent and bounced and I'm on the postmaster alias. Thunderbird was able to do a mass select of one of the two messages, and deleted 65,000, but after that it locked up. I ended up firing up Pine to do the final 65,000...whereas TBird had had mulitple imap sessions (and failed), Pine only had one and did the job. And even after I had done the mass delete of the other 65,000 and the inbox was down to 2000 messages, TBird was still hiding under the covers and telling me there were still 135,000 messages. In the end, I had to kill the TBird profile for that account and recreate it. Is there a simple robust IMAP client to replace Pine (which I *think* is no longer supported)? GUI or TTY session? I'm wondering if there is something we can tell users to use when Things Are Dire. GUI would be better since it removes one of the few remaining reasons for a logon server -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] [PATCH] drop root privileges on solaris, request for testing
by Andrey Panin 18 Dec '08

18 Dec '08

Hello all, this patch allows master process to drop more root priveleges under Solaris. My limited testing shows that code works, but I'm not sure that defined privilege set is permissive enough for dovecot. Unfortunately I have no root access to our Solaris servers to really test it. So if someone is ready to test this patch please do it :) Best regards.

[Dovecot] Dovecot imap processes pinning CPU
by David Rosenstrauch 18 Dec '08

18 Dec '08

In recent days, dovecot's "imap" processes keep getting stuck. Each time I check my server (running dovecot 1.1.7) there's a bunch of "imap" processes (sometimes 2 of them, sometimes 4, sometimes 6) that are using all of the box's CPU. And worse, there's no way to kill the processes either (neither kill -15 or kill -9 works), which means that I wind up having to reboot the box every time this happens. REALLY irritating. I don't normally even *see* the imap processes in htop, as I think they're pretty short lived. And I'm not sure what they're looping trying to do. My debugging skills on Linux are a bit weak, and so I don't know how to look at the process and see what it's doing. Also, not sure what's changed on my system to cause this, as this is definitely a recent problem. Maybe the upgrade to Thunderbird 2.0.0.18 (since I usually use T'Bird to access my email). I don't seem to run into this problem when I use Squirrelmail. Anyone have any idea what the problem might be? Or, if not, then suggestions on how I might be able to debug the situation myself? TIA, DR

[Dovecot] SSL Certificate Authentication
by Anthony Davies 18 Dec '08

18 Dec '08

Hi Guys, I am using the SSL Client Certificate authentication method for my Dovecot instance, however rather then just requiring the client certificate it also prompts me for my user password. My certificate was securely generated on a smart card and is passphrase protected so I would like to stop having to enter my certificate passphrase and my user password to collect my mail. Where abouts in the config file can I resolve this issue? Cheers, Tony Davies

[Dovecot] v1.1.6 released
by Timo Sirainen 17 Dec '08

17 Dec '08

http://dovecot.org/releases/1.1/dovecot-1.1.6.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.6.tar.gz.sig The invalid message address parsing bug is pretty important since it allows a remote user to send broken mail headers and prevent the recipient from accessing the mailbox afterwards, because the process will always just crash trying to parse the header. This is assuming that the IMAP client uses FETCH ENVELOPE command, not all do. Note that it doesn't affect versions older than v1.1.4. + dovecot -n and -a now prints some system information at the top. + More error/debug message logging improvements. - pop3-login: Fixed assert-crash if a client sent USER+PASS+USER+PASS commands in the same IP packet. - Parsing an invalid message address like "From: (" caused an assert-crash in v1.1.4 and v1.1.5. - Folding whitespace wasn't handled correctly inside quoted-strings, causing some messages to be parsed incorrectly. - mbox: Fixed saving messages that begin with a valid From_-line.

http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha5.tar.gz http://dovecot.org/releases/1.2/alpha/dovecot-1.2.alpha5.tar.gz.sig It's been a while since alpha4 so I thought I'd release a new one while waiting for Apple's patches.. - mbox fixes. - Lots of Solr fixes - Virtual mailboxes + Solr works now nicely instead of duplicating the indexed data. - Added alias_for setting for namespaces, also useful to avoid duplication of Solr indexed data if you have multiple namespaces that point to the same location (e.g. both "" prefix and "INBOX." prefix compatibility). - %variables now support long %{variable_names}: http://wiki.dovecot.org/Variables. I was planning on using these to redesign LDAP configuration (e.g. home=/var/mail/%{ldap:homeDirectory}) - imap/pop3 proxy: Support master user logins. - Improved some error messages

[Dovecot] Syncing several emails accounts with offlineimap and dovecot
by Joe Bloggs 17 Dec '08

17 Dec '08

Hi, I have just installed dovecot and offlineimap on my laptop for syncing with my gmail, and reading in gnus, as outlined in this article: http://sachachua.com/wp/2008/05/08/geek-how-to-use-offlineimap-and-the-dove… I am using Debian Etch, and I am the only user. The only change I made to the default dovecot.conf file was to set: mail_location = maildir:~/MailDir I read that gnus doesn't handle Maildir very well, so I need to connect directly to dovecot, and this is what I have specified in my offlinemap conf file: [Repository Local] type = IMAP remotehost = localhost port = 143 remoteuser = me remotepass = secret I want to sync my other online email accounts aswell. Can anyone tell me how to do this? Thanks.

[Dovecot] dovecot >1.1.3 + antispam plugin issues
by Marcin Rzepecki 16 Dec '08

16 Dec '08

Hello, i have following problems using dovecot-antispam plugin (Dovecot >1.1.3, FreeBSD 8.0-Current, dovecot-antispam 1.0/1.1) dovecot-antispam compiled using dspam-exec/mailtrain, with/wo debugging (i've tried all possibilities) When i try to move message to SPAM folder (using dspam-exec backend) i'm getting IMAP error: antispam signature not found and in dovecot logs: Nov 23 23:44:24 freebsd dovecot: IMAP(mr): Next message unexpectedly lost from 2708619 Using mail backend gives this error too(only IMAP error changes: failed to read mail beggining). Commenting out following code in mbox_read_from_line function (in src/lib-storage/index/mbox/istream-raw-mbox.c) helped and plugin was working correctly, but only with Dovecot <=1.1.3. if (stream->istream.v_offset - rstream->hdr_offset + new_pos > rstream->mail_size) { /* istream_raw_mbox_set_next_offset() used invalid cached next_offset? */ i_error("Next message unexpectedly lost from %"PRIuUOFF_T, rstream->hdr_offset + rstream->mail_size); rstream->eof = TRUE; rstream->corrupted = TRUE; rstream->istream.istream.stream_errno = EINVAL; stream->pos = 0; return -1; } Now, with versions >1.1.3 this won't helps and plugin fails. Anyone knows how to get it working? I would like to upgrade to newest dovecot release Best regards, mr

[Dovecot] Problem with managesieve (and virtual users?)
by Mike Constabel 15 Dec '08

Hello, I use the debian packages from http://xi.rename-it.nl/debian/ version 1.1.7-0~auto+17 If I put a sieve script into /home/vmail/sieve-scripts/test.de/test.sieve it is used, so cmusieve works.
