[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] Red Hat ES 4 - dovecot-auth: Unknown password scheme SMD5
by mel llaguno 01 Oct '05

01 Oct '05

I have a couple of questions regarding the default dovecot packaged with RedHat ES 4. The dovecot version is 0.99.11-2.EL4.1 which I assume is considerably behind the current stable version of 0.99.14. Is it the fact that I am using an older version of dovecot that SSHA passwords in an openldap directory are not recognized and give the following error: dovecot-auth: Unknown password scheme SMD5 ? LDAP is working as expected for NFS maildirs. I have dovecot 0.99.13 working on fedora core 3, but the stability of fedora leaves much to be desired and would like to get a stable, low maintenance install of dovecot on an enterprise supported linux. Redhat does not have packages for 0.99.14 and I would rather compile from source if possible. I've specified --with-ldap as part of the configure script, but am wondering if there is anything more to add to support SSHA passwords. Until dovecot 1.0 is proven in the field, it is not a consideration for the production environment this server is being used for. Any help with this matter would be greatly appreciated. TIA, Mel Llaguno

[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.

[Dovecot] ManageSIEVE services with Dovecot cvs-LDA?
by OpenMacNews 28 Sep '05

28 Sep '05

hi all, has anyone had any success in getting the current dovecot cvs-lda's implementation of CyrusSIEVE responding to a ManageSIEVE client? in particular, i'm hoping that one can use, e.g., Mulberry's Client- & Server-side sieve editor: <http://www.cyrusoft.com/sieve/sievescreens.html> if i telnet to my dovecot box's sieve port ( = 2000) i get no response at all ... telnet localhost 2000 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host net-stat shows nothing on port 2000, and, afaik, there's no mention of a server on the wiki ... so i'm either doing something wrong, or "it" is simply not there. has a sieve server been implemented? any plans? thx! richard
