[Dovecot] mailing lists and Dovecot deliver (lda)
by Roderick A. Anderson 11 Feb '09

11 Feb '09

I'm trying to figure out a way, or if it is even possible, to use mailing list software (majordomo2) on a Postfix + Dovecot + virtual mailboxes system. And where I should be looking. The examples on the Postfix site don't seem to address a purely virtual mailboxes system and I haven't found anything about doing it with deliver. I think I'm at the wrong tree (Dovecot deliver) and should be pestering the Postfix list. FTR, I host some sites for not-for-profits and they have asked about setting up lists. So far I've dodged the question but would like to attempt it now. Thanks, Rod --

[Dovecot] I've moved to US
by Timo Sirainen 10 Feb '09

10 Feb '09

I thought about saying this in v1.2.beta1 release annoouncement, but looks like it'll take a few more days. So I've moved to Blacksburg, Virginia and I'm now working for Mailtrust the rest of this year. Here's some talk about it: http://mailtrust.com/blog (A bit stupid looking picture, but then again all my pictures seem to be that way so I didn't bother getting a new one taken.) And if it's not clear from that blog: Pretty much everything I do here will be Dovecot improvements that will be released as open source. Mailtrust has actually been paying for Dovecot features for about 3 years now.

[Dovecot] redelivered mail results in mail-forwarding-loop
by Reto Glauser 10 Feb '09

10 Feb '09

I try to redeliver mail for the following reason: Once in a while a user receives a mail which isn't correctly recognised as SPAM/HAM. He'll move the mail into a specific folder (say: retrain-as-spam/retrain-as-ham) and a script will retrain the mail. What I'd like to do is to redeliver the mail in order for correct (re)delivery (e.g. sieve scripts). Using sendmail to redeliver the mail I'm able to re-run the spam tests which will add it's SPAM headers and dovecot/sieve will be able to correctly file the message. I tried to just resend the mail: # /usr/sbin/sendmail -f foo@bar -v -oi foo@bar < mail but this results in a Diagnostic-Code: X-Postfix; delivery via dovecot: mail forwarding loop for foo@bar The problem is that the mail already has a "Delivered-To: foo@bar" line. The above is working when the "Delivered-To" line is being removed, and my question is if this can't be done automatically?

[Dovecot] [Fwd: Re: dovecot logs to audit.log not to maillog]
by Ralf Heidenreich 10 Feb '09

Hello, now I have done this: under http://wiki.dovecot.org/Logging?highlight=(logging) Rotating Logs is the following string ----------------------- /bin/kill -USR1 `cat /var/run/dovecot/master.pid 2>/dev/null` 2> /dev/null || true ------------------------ This string I have insert in /etc/logrotate.d/syslog under the lines: postrotate /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true So Dovecot will be restarted, after the log rotates.

[Dovecot] Dovecot / Exim with Multiple Domiains
by Marc Perkel 10 Feb '09

10 Feb '09

I'm using a very old scheme for doing multiple domains using an old Linuxconf based setup. Each domain has it's own passwd/shadow file. It works but I need something new and modern and has a web interface and perhaps a mysql backend or something else good. So - what are people using out there for managing email users and domains? Thanks in advance.

[Dovecot] Imap unlink "failed, is a directory".
by Dovecot＠corwyn.net 10 Feb '09

Dovecot 1.1.8-0_85.el5 I'm seeing this set of messages repeat every 15 min. My best guess is the user tried to delete an imap folder and is failing? Feb 9 20:05:58 mailserver dovecot: imap-login: Login: user=<user(a)example.com>, method=PLAIN, rip=10.0.0.1, lip=192.168.250.80, TLS Feb 9 20:05:58 mailserver dovecot: IMAP(user(a)example.com): unlink(/var/spool/mail/example.com/user/Maildir/cur/cur:2,ST) failed: Is a directory Feb 9 20:05:58 mailserver dovecot: IMAP(user(a)example.com): unlink(/var/spool/mail/example.com/user/Maildir/cur/new:2,ST) failed: Is a directory Feb 9 20:05:58 mailserver dovecot: IMAP(user(a)example.com): Disconnected: Logged out bytes=66/623 From here: http://wiki.dovecot.org/VirtualUsers#homedirs I suspect it's a problem with access to the home directory.

[Dovecot] Authentication woes.
by Roderick A. Anderson 10 Feb '09

10 Feb '09

I'm still searching but hoping someone can offer a clue-stick. Long story short! I had a server crash suddenly and all I can get at are the files. Built a new host and copied the data and config files over, correcting ownership and permissions (hopefully) as I went. But now I can't get logged in. Messages in /var/log/dovecot/dovecot-info.log, without saslauthd running, are like this. dovecot: Feb 03 08:55:46 Info: auth(default): passwd-file(raanders(a)aesoft-sbcs.com,66.193.34.88): no passwd file: username_format=raanders /var/mail/vhosts/aesoft-sbcs.com/passwd dovecot: Feb 03 08:55:48 Info: auth(default): client out: FAIL 1 user=raanders(a)aesoft-sbcs.com dovecot: Feb 03 08:55:48 Info: auth(default): client in: AUTH 2 PLAIN service=IMAP secured lip=216.64.180.226 rip=66.193.34.88 resp=AHJhYW5kZXJzQGFlc29mdC1zYmNzLmNvbQBrNnpiZTQy dovecot: Feb 03 08:55:48 Info: auth(default): passwd-file(raanders(a)aesoft-sbcs.com,66.193.34.88): no passwd file: username_format=raanders /var/mail/vhosts/aesoft-sbcs.com/passwd dovecot: Feb 03 08:55:50 Info: auth(default): client out: FAIL 2 user=raanders(a)aesoft-sbcs.com dovecot: Feb 03 08:55:54 Info: imap-login: Aborted login: user=<raanders(a)aesoft-sbcs.com>, method=PLAIN, rip=66.193.34.88, lip=216.64.180.226, TLS The passwd file exists and I'm using the correct password. dovecot -n as an attachment.

[Dovecot] Dovecot 1.1.11 segfaults on auth configuration error
by Sebastian Kayser 10 Feb '09

10 Feb '09

Hi, i have compiled & packaged Dovecot 1.1.11 on Solaris 8 x86 with Sun Studio 11 and installed the result on Solaris 10 x86 zone. When i now configure auth mechanisms other than "login" or "plain" while only providing pam as the passdb, Dovecot segfaults on startup. I know that my configuration is wrong here, but i guess this still qualifies as a bug. Remedy would be appreciated. # /opt/csw/sbin/dovecot -F dovecot: Feb 06 22:56:24 Info: dovecot v1.1.11 starting up dovecot: Feb 06 22:56:25 Error: child 26870 (auth) returned error 89 (Fatal failure) Segmentation Fault (core dumped) # /opt/SUNWspro/bin/dbx -f /opt/csw/sbin/dovecot core (dbx) where =>[1] hash_lookup(table = (nil), key = 0x68f6), line 159 in "hash.c" [2] child_process_lookup(pid = 26870), line 31 in "child-process.c" [3] log_it(log_io = 0x80b8598, line = 0x80b7d4a "DIGEST-MD5 mechanism can't be supported with given passdbs", continues = 0), line 129 in "log.c" [4] log_write_pending(log_io = 0x80b8598), line 52 in "log.c" [5] log_read(log_io = 0x80b8598), line 191 in "log.c" [6] log_deinit(), line 331 in "log.c" [7] auth_process_destroy(p = 0x80b86f8), line 357 in "auth-process.c" [8] auth_process_input(process = 0x80b86f8), line 244 in "auth-process.c" [9] io_loop_handler_run(ioloop = 0x80b3518), line 204 in "ioloop-poll.c" [10] io_loop_run(ioloop = 0x80b3518), line 336 in "ioloop.c" [11] main(argc = 2, argv = 0x80478dc), line 599 in "main.c" # /opt/csw/sbin/dovecot -n # 1.1.11: /etc/opt/csw/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc log_path: /dev/stderr login_dir: /var/opt/csw/run/dovecot/login login_executable: /opt/csw/libexec/dovecot/imap-login auth default: mechanisms: plain digest-md5 debug: yes passdb: driver: pam userdb: driver: passwd Please let me know in case there is any other information required to nail down the culprit.

[Dovecot] [patch] 'c' and 'd' in setacl
by Sascha Wilde 09 Feb '09

09 Feb '09

Hi Timo, Hi *, I just recognized that the new imap-acl plugin in dovecot 1.2 does not know the obsolete rights 'd' and 'c' when setting. According to RFC 4314 section 2.1.1.: If a client includes the "d" right in a rights list, then it MUST be treated as if the client had included every member of the "delete" right. and If a client includes the "c" right in a rights list, then it MUST be treated as if the client had included every member of the "create" right. Unfortunatly there are actually clients which depend on this behavior. I attached a rather rough[0] patch which implements this. cheers sascha [0] I don't like the use of static indexes witch imap_acl_letter_map but currently I wasn't able to decide on a more elegant solution. -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Rebuild folder listing?
by Roderick A. Anderson 09 Feb '09

09 Feb '09

I don't know what to call what I'm trying to do so I'll explain the situation. I had a total complete crash of the Linux-Vserver system that was hosting a Postfix+Dovecot guest with a three domains and 1-5 accounts per domain. Lots of mail though. Before it completely melted down I as able to get to the data (messages) and save them and the configuration files for both Dovecot and Postfix. I now have a replacement system up and running and have copied the directories onto it. I can log in to the accounts but I don't see the folders (I use Thunderbird as a MUA). Attempts to "subscribe" and "refresh" the list give me no results. No list of folders. What should I do? I'm thinking I could delete the dovecot files: dovecot.index, dovecot.index.cache, dovecot.index.log, dovecot-uidlist, subscriptions, and while I'm at it possibly dovecot-keywords. Then access the account(s) and Dovecot will rebuild them with the true/correct information. Am I heading anywhere near the right direction? TIA, Rod --
