Fwd: [Dovecot] Very slow select() command on large mailboxes
by Sebastjan Trepca 22 Jul '05

22 Jul '05

Maildir, its easier to export and can support hardlinks. What kind of optimizations did you have in mind? What's the downside of mbox? Problem is that version 1.0 is only test release for now.

[Dovecot] configuration of user_global_uid and user_global_gid
by KATOH Yasufumi 22 Jul '05

Hi. I'm configuring LDAP auth with dovecot (cvs trunk at 14, July) as follows: /etc/dovecot/dovecot.conf: passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } /etc/dovecot/dovecot-ldap.conf: user_attrs = mail,homeDirectory,mailbox,,, user_global_uid = 10000 user_global_gid = 1000 But "user_global_uid" and "user_global_gid" definition does not work. dovecot: Jul 14 11:50:36 Error: auth(default): ldap(test(a)example.jp,127.0.0.1): ui d not in user_attrs and no default given in user_global_uid dovecot: Jul 14 11:50:36 Error: auth(default): ldap(test(a)example.jp,127.0.0.1): gi d not in user_attrs and no default given in user_global_gid How do I configure to enable "user_global_uid" and "user_global_gid"? Does my configuration have any problem? -- karma(a)jazz.email.ne.jp / KATOH Yasufumi

[Dovecot] Changing port?
by Matt Juszczak 22 Jul '05

22 Jul '05

Hi all, Trying to setup a test copy of dovecot on my box before I "really" use it. I have it installed into a test dir (/usr/local/dovecot instead of /usr/local), and I've got a config file with valid dirs, etc. Only thing is ... I can't find a way to set the port in the protocol pop3 {} section. Its documented in the "listen" directive area at the top of the config file that says its possible, but no other mention of it is ever made. How can I make my test copy listen on port 111? :) Regards, Matt

[Dovecot] Can't connect to auth server
by Todd Burroughs 22 Jul '05

22 Jul '05

I've been seeing these errors intermittently for a while now. Here's an example from the logs: dovecot: Jul 12 15:59:05 Error: imap-login: Can't connect to auth server at default: Resource temporarily unavailable The error is EAGAIN. Sometimes it will resolve itself after a few minutes and sometimes it needs to be restarted (it may fix itself, I usually get a phone call if it goes on for very long). I've looked while the problem is occuring and dovecot and dovecot-auth don't have an excessive number of file descriptors open, maybe 10 or 20. Any ideas or anything else to look at? The system is SuSE Linux 9.2 running kernel 2.6.x. We have seen some odd things happen with these systems, so it is possible that it is not dovecot. The kernel doesn't log anything unusual and other processes seem happy. Todd

[Dovecot] test76-77 dies at SIGHUP
by Johan Fredin 22 Jul '05

22 Jul '05

Hello people This is on OpenBSD/sparc64. After chickening along with 0.99 for a while, I finally upgraded to 1.0-test. I started out with test73, which worked fine. With the upgrade to test76, I lost the ability to SIGHUP dovecot when I rotated it's logfile. Dovecot would just die abruptly, not a trace in the log. I just upgraded to test77, but the problem is still there. I've put up my logfile and the last bit of a ktrace here: http://legonet.org/~griffin/tmp/dovecot/ The ktrace is partitial mostly because it contains usernames, I can edit those out and upload the hole shebang if that'll help. I'd appreciate any tips/pointers on this one! /Johan

[Dovecot] test77, yahoo & fetchmail
by Chris Spiegel 22 Jul '05

22 Jul '05

I've run into a rather narrowly scoped problem .. On test77 and test78, mails from Yahoo's webmail are seen, by fetchmail using imaps, to have a 0-length body. When fetching, it claims "0 body octets". Other mail clients (mutt, kmail) can view the messages fine. pop3s retrieval works as well. Every other email I've received so far works fine. It's just those sent by Yahoo's webmail service that have the problem. imaps retrieval does, however, work fine with test76. Let me know if there's anything I can do to help track this down. Thanks, Chris

----- Original Message ----- From: nickr To: dovecot(a)dovecot.org Sent: Thursday, July 21, 2005 4:19 PM Subject: Dovecot 0.99.11 config I am at wits end...So far it seems dovecot is light years ahead of UW-IMAP. Glad to have UW-IMAP behind me...well almost. My setup = Sendmail 8.13.4 with Procmail delivery to /var/spool/mail/<userfile> openssl 0.9.8 dovecot 0.99.11 I want to continue to use the standard mbox with all the user's mail stored in /var/spool/mail/<userfile>. User's are known to this mail server via NIS and ALL data is mounted accress NFS in read only mode on this machine, including ~home directories. I want to run dovecot like UW-IMAP...trying to keep it simple-->mail delivery to mbox /var/spool/mail/<username>. My /etc/dovecot.conf: I tried both default_ mail_env = INBOX:/var/spool/mail/%u:INBOX:INDEX=MEMORY with and with out the INBOX:INDEX=MEMORY I want to disable the indicies feature. We don't need it we're about 20 engineers or so who want to continue to use the /var/spool/mail mbox-the original Sendmail location. Most users are downloading every piece of mail through OutHouse or Pine, aka OutLook. I keep getting failed to create storage meaages in /var/log/maillog...

[Dovecot] linux 2.4 vs 2.6 kernel
by vmstech 20 Jul '05

20 Jul '05

hi I read ( I think in dovecot wiki) that ext2 or ext3 fs on a 2.4 kernel can get slow due to the number of files in a directory. Does anyone know if kernel 2.6 has similar limitation? I'm not at that point now, but before the box goes live, I'm wondering if I should resolve that. Glenn

[Dovecot] Debian has moved to 1.0stable
by Jaldhar H. Vyas 20 Jul '05

20 Jul '05

Now that sarge has been released, I have as requested moved Debians' Dovecot packages to the 1.0stable branch. Most of the work was actually done by Fabio Tranchitella who is joining me as co-maintainer. The new packages should be available in sid later today. A backport to sarge will also be provided as soon as I can get around to it. Please report all problems to the Debian bug tracking system (see http://bugs.debian.org for instructions or use the reportbug package) not to me directly so that Fabio can also see. -- Jaldhar H.
