[Dovecot] Is anyone using the dspam plugin for dovecot 1.1?
by Lars Stavholm 24 Sep '07

I'm about to try to adjust the dspam plugin code to dovecot-1.1, but before starting out on this, I thought I'd ask the list: anyone done it already? /L

[Dovecot] SEARCH NOT not working
by Julian Cowley 24 Sep '07

24 Sep '07

I think I've found the source of a bug which I first saw when running dovecot and pine (or alpine), which I finally tracked down by doing a protocol trace. In the IMAP session, the SEARCH command appears to have a problem with sets of messages and/or the NOT operator. Probably the best way to show this is by doing operations on a folder with ten messages in it. a select ten * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 10 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1190450101] UIDs valid * OK [UIDNEXT 11] Predicted next UID a OK [READ-WRITE] Select completed. Now, start doing some basic searches using message sets: b search (1:10) * SEARCH 1 2 3 4 5 6 7 8 9 10 b OK Search completed. OK, so far so good. Try the inverse: c search not (1:10) * SEARCH c OK Search completed. OK. d search not (1,10) * SEARCH d OK Search completed. Hmm, should have output 2..9. e search not (2,10) * SEARCH 1 e OK Search completed. Hmm.. that should have been 1, 3..9. f search not (2:10) * SEARCH 1 f OK Search completed. OK, expected. g search not (1,9) * SEARCH 10 g OK Search completed. Seems to affect other end of the range as well. h search not (2,9) * SEARCH 1 3 4 5 6 7 8 10 h OK Search completed. OK working again.

[Dovecot] dovecot with virtual and local users?
by Patrick Winnertz 23 Sep '07

23 Sep '07

Hello, I googled for a while in order to find a solution to make dovecot work with local and virtual users. My Mailserver setup looks like the following: virtual users are stored in a mysql database, and having their Mailbox here: /srv/mail/$domain/$uid/ Local users have a Maildir folder in their home directory. The only point i found in the web concerning this issue is this post here: http://www.dovecot.org/list/dovecot/2006-November/017478.html but I failed to understand the user_query. Can somebody who has such a setup running, or know how such a setup will work give me an advice, or a good point to read? Greetings Patrick ps: Please cc me, I'm not subscribed. -- .''`.

Re: [Dovecot] v1.1.beta1 released

There are two things: From the logs: 1) dovecot: fd limit 256 is lower than what Dovecot can use under full load (more than 1152). Either grow the limit or change login_max_processes_count and max_mail_processes settings this is of course NOT a dovecot problem, it is just being nice and saying it can use more than the OS X defaults for open files. The next come from using the new Dovecot LDA: in trying to send mail, the following error occurs and I have not been able to find the setting to change this 2) postfix/qmgr[25767]: 2459A37F612: from=<from-email-address>, size=1226, nrcpt=1 (queue active) deliver(to-email-address): auth input: to-email-address deliver(to-email-address): auth input: uid=1000 deliver(to-email-address): auth input: gid=1000 deliver(to-email-address): auth input: home=path/to/ deliver(to-email-address): setgroups() failed: Operation not permitted postfix/pipe[6505]: 2459A37F612: to=<to-email-address>, relay=dovecot, delay=984, delays=984/0.03/0/0.06, dsn=4.3.0, status=deferred (temporary failure) The solution so far is to go back to using the Postfix Deliver option. Where is the setgroups option being set in the LDA? Thank for you hard work!! Jerry Yeager

[Dovecot] kmail + IMAPS
by Timothy Murphy 23 Sep '07

23 Sep '07

I have dovecot IMAPS + kmail working perfectly on two laptops - I'm using one now - but I just tried starting it on a third laptop, and cannot get it running; kmail on the third laptop just waits indefinitely, saying "Retrieving Folder Contents Please wait ...". All 3 laptops are running Fedora 7, with more or less the same packages, all updated. (1) I suspect the problem lies with authentication. But how can I test this? Running "telnet <server> 993" gets the same response on all 3 laptops: [tim@elizabeth ~]$ telnet www.*.com 993 Trying 86.*.*.228... Connected to www.*.com. Escape character is '^]'. with no further response until I press ^]. I looked at <http://wiki.dovecot.org/TestInstallation> but this seems only to apply to IMAP on port 143. (2) kmail has an option to "Check What the Server Supports" under the Security tag, but pressing this just returns without any message, leaving whatever settings as they are. (On the laptops where kmail is working as an IMAPS client, the settings are changed to "Use TLS ..." and "Clear text".) I realise this is probably a kmail question, but shouldn't clicking on this option return some warning if it does not work? (3) I guess I don't understand exactly how TLS authentication works. Does installing openssl set up the correct certificates on server and client? Is there any documentation on this? Any suggestions or enlightenment gratefully received.

[Dovecot] recipient delimiter results in sieve errors
by Gregory Mokhin 23 Sep '07

23 Sep '07

Hello, I'm using dovecot 1.0.3 and Dovecot Sieve plugin 1.0.2. Sieve script works fine with normal addresses, like user@domain.., and messages marked with "X-Spam-Flag: YES" are delivered directly to INBOX.Spam. To make deliver understand recipient_delimiter I tried two methods, the first one as per wiki (tweaking postfix master.cf), and the second one by tweaking dovecot-sql.conf (the main idea is to use concat(substring_index('%n',"+',1),'@','%d') for the username). Both methods work good. However when deliver processes sieve script for the addresses with a delimiter, user+ext(a)domain.tld, there is an error: deliver(test@k..): Info: cmusieve: Using sieve path: /home/vmail/.dovecot.sieve deliver(test@k..): Info: cmusieve: Executing script /home/vmail/.dovecot.sievec deliver(test@k..): Info: sieve runtime error: Keep: Generic Error deliver(test@k..): Error: sieve_execute_bytecode(/home/vmail/.dovecot.sievec) failed deliver(test@k..): Info: msgid=<..@mail...>: saved mail to INBOX In that case message is delivered to INBOX, not to INBOX.Spam Regards, Gregory

[Dovecot] Binary packagers: BSD license issues
by Timo Sirainen 23 Sep '07

23 Sep '07

Adding this SHA256 code made me read the BSD license once again. It says: * 2. Redistributions in binary form must reproduce the above copyright * notice, this list of conditions and the following disclaimer in the * documentation and/or other materials provided with the distribution. Then there are a few files from Cyrus as well which contain: * 4. Redistributions of any form whatsoever must retain the following * acknowledgment: * "This product includes software developed by Computing Services * at Carnegie Mellon University (http://www.cmu.edu/computing/)" And something similar in utc-mktime.c for Berkeley university as well. I think I'd really like to get rid of those base64.c and utc-mktime.c exceptions.. There's probably also an easier/faster way to implement utc_mktime(). Anyway.. Currently these copyrights or acknowledgments aren't listed anywhere else than in the source files. I don't know if binary packagers have added those, but somehow I doubt it. So I think I should add these to COPYING file somehow. Any suggestions?
