[Dovecot] using local-part delimiters in LDA delivery?
by OpenMacNews 03 Oct '05

03 Oct '05

hi all, i've exim 4.53RC2 + dovecot-cvs on OSX 10.4.2. i'm working on implementing recipient-delimiters for delivery from exim to a user's imap store using dovecot's cvs-lda. reading on the wiki (Jakob's latest comments?): " ... the part after the delimiter is passed to the lda as an additional parameter. so dovecot-lda should handle that parameter and leave the separator handling to the MTA. The MTA has to handle it anyway." it looks likes it's possible ... with appropriate changes in exim to my router: dovecot_localuser: driver = accept domains = +local_domains local_part_suffix = +* local_part_suffix_optional transport = dovecot_lda and transport: dovecot_lda: driver = pipe command = /.../deliver \ -c /.../dovecot-deliver.conf \ -d $local_part@$domain message_prefix = "" message_suffix = "" delivery_date_add envelope_to_add return_path_add log_output user = MY_MAIL_USER i'd like to be able to build delivery conditions in dovecot so that, e.g. mail to: bob(a)mydomain.com is delivered to "bob"'s default INBOX. but, mail to: bob+spam(a)mydomain.com is delivered to any specified (either a server-wide common relative path, or a user-specified) SUBFOLDER, say "bob/INBOX/.../.../spam_to_look_at" defined by a dovecot-rule invoked by the delimiter "spam" ... this is a little different than the approach Mark mentioned of delivering directly to folder_name specified by the local-part-after-delimiter ... questions: (1) until the two conf files merge, i'm guessing there needs to be some conditional logic in dovecot-deliver.conf rather than in dovecot.conf. correct? or should i be thinking SIEVE rules? (2) exactly WHAT "additional part" do i grab in dovecot? thx! richard

by Riccardo Bini 01 Oct '05

01 Oct '05

Hi all, I have a little request: It's possible to have the full user name in the logs? I mean this: dovecot: pop3(info): Logout. top=0/0, retr=0/ del=0/0, size=0 info(a)example.com instead of info. I use 10 real users and many vpopmail users. I get in the log too many (info)... 8-( Thx Rick

[Dovecot] sudo /etc/init.d/dovecot start doesn't work
by Sam Fung 01 Oct '05

I've been trying to get dovecot working with postfix with virtual domain setting. I noticed that if I started dovecot with "sudo /usr/sbin/dovecot", everything would work fine. But if I started with "sudo /etc/init.d/dovecot start", I would get the following permission error. I checked "ps -ef | grep dovecot" and didn't find anything different. Sep 29 16:54:35 localhost imap-login: Login: xyz(a)example.com [::ffff: 192.168.0.4 <http://192.168.0.4>] Sep 29 16:54:36 localhost imap(xyz(a)example.com): mkdir_parents(/var/spool /virtual_mailboxes/example.com/xyz/.imap/INBOX) failed: Permission denied Here's the directory for storing virtual domain email.

[Dovecot] Using procmail with virtual users...
by Arnaud Guiton 01 Oct '05

01 Oct '05

Hello all, I've a working dovecot installation on my machine, using exim3, virtual users and maildirs. I would like to add procmailrc rules for these (virtual) users, but i've not succeeded with that. The authentication is done with a passwd-file looking like this : testuser:password:uid:gid::/home/mail/testuser::chroot:maildir:/home/mail/testuser/Maildir/ i've put .procmailrc files in /home/mail/testuser/.procmailrc, but it this not taken into account, because the MTA never calls the procmail router as it resides after the dovecot one. How is the proper way of using procmail with virtual user (and is it at least possible) ? Thanks, -- Arnaud

[Dovecot] Can't connect to auth server at default: Connection refused
by Chris Wakelin 30 Sep '05

30 Sep '05

We've being running with Dovecot 1.0-stable since Tuesday, and on the whole it's gone very well (meaning nobody's noticed!). My best estimate is we're using half the disk accesses and 2/3 the CPU of UW-IMAP/Qpopper. We've quite a mixture of error messages in the logs, the most worrying of which is that several times we've had a few seconds of "xxx-login: Can't connect to auth server at default: Connection refused" (where xxx is pop or imap). It seems to sort itself out shortly afterwards. We're using userdb=passwd, passdb=passwd (authenticating via NIS). From Tuesday we'll be using passdb=pam (pam_ldap to Active Directory). My first guess is that some dovecot-auth process stops responding and gets killed off. Is this right? Other errors we're seeing include 1) pread_full() failed with mbox file /export/mail/c/37/sau04djp/INBOX: No such file or directory (when there is!) 2) mbox sync: UID inserted in the middle of mailbox (especially with .prayer folders - configuration folders for our Webmail) 3) file mbox-lock.c: line 505 (mbox_lock): assertion failed: (lock_type == F_RDLCK || ibox->mbox_lock_type != F_RDLCK) presumably some of these are fixed in alpha2.

[Dovecot] Problem running latest 1.0-alpha3
by dovecot＠spam.turbolink.net 30 Sep '05

30 Sep '05

I've tried upgrading from dovecot-1.0 stable to the latest dovecot-1.0.alpha3. I've done a configure with: ./configure --with-notify=none --with-ioloop=poll And all I get is this when I run: dovecot: Sep 29 16:45:28 Info: Dovecot v1.0.alpha3 starting up dovecot: Sep 29 16:45:29 Error: Auth process died too early - shutting down dovecot: Sep 29 16:45:29 Error: auth(default): Fatal: sigaction(SIGRTMIN) failed: Invalid argument dovecot: Sep 29 16:45:29 Error: child 4828 (auth) returned error 89 Linux kernel 2.4.24, FS in use are XFS and NFS Any clues? - Mike

[Dovecot] redirect and sieve BUG
by List Subscriptions [Obfusc8.Org] 30 Sep '05

30 Sep '05

I've only just subscribed to the list, but in reading through the back-issues have come across a bug with dovecot-lda that was reported previously, and I can reproduce. Using dovecot-lda CVS with Revision 1.21 of deliver.c (as newer versions won't compile against 1.0-alpha3), with dovecot 1.0-alpha3 and postfix 2.1.5 Rredirects mangle some headers - the 'To:' header ends up as: To: undisclosed-recipients: ; And there is no subject header. Running sendmail from the cmdline with: sendmail -i -f '<>' -- destination at address.com <msgtext> as suggested to test by *Timo Sirainen *results in a correctly formatted message. The mail_send_forward function in mail-send.c looks sane from what I can see, but then I'm not a C coder... Any clues guys? Cheers, Pete

[Dovecot] Maildir and counting inodes
by Andy Cravens 30 Sep '05

30 Sep '05

I've been testing with alpha 3 and I am about ready to go production. I am switching from mbox to maildir and I'd like to know if there is a formula or rule of thumb for determining if your file system will have enough inodes to handle all the mail message files. I could write a script to look at each user's mbox files, count the number messages and calculate the average number of emails per user, then add a fudge factor for expected growth. However, I doubt anybody actually goes to this much trouble to plan ahead. Or do they? I'm running Solaris 9 and when I created the file system I just used the defaults. If I need to change anything, I'd rather do it before going production. Thanks for any info you can provide on this subject.
