[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.

> > >> ------------------------------------------------------------------------ > We were posed with the same dilemma, but it was due to the need to stick with RHEL supplied packages (ReiserFS does not come with RHEL) that we stayed with ext3. Our old production mail server, running our in-house flavour of Linux, was based on the 2.4 kernel with ReiserFS. We load tested Dovecot with maildir under RHEL3 (2.4 kernel) using ext3 and found it was unable to standup to our requirements. In part this was due to an inordinate imap-login / pop-login processes being created and hanging around under RHEL3. Using RHEL4 (2.6 kernel), we found we were able to handle the required load - this is the configuration we went live with. Processes ended cleanly too (result of the improved schedular and how it interacted with our IBM x445 and its NUMA architecture?) and the I/O issues seemed to have been resolved - ext3 was fine. >> Subject: >> Re: [Dovecot] linux 2.4 vs 2.6 kernel >> From: >> Marc Perkel <marc(a)perkel.com> >> Date: >> Mon, 18 Jul 2005 18:33:54 -0700 >> >> CC: >> dovecot(a)dovecot.org >> >> >> >> >> Curtis Maloney wrote: >> >>> Marc Perkel wrote: >>> >>>> Actually - yes.

[Dovecot] Compiling under Fedora Core 4 - Problem
by Marc Perkel 19 Jul '05

19 Jul '05

OK - trying to migrate to dovecot and I like what I see so far, but having a hard time getting it to work. I decided to go with the 1.0 version because I need to get away from the ~/Mail namespace. I'm trying to port from a Linuxconf virtual WU-IMAP type config. So - I compiled but then decided I wanted mysql so I tried to reconfigure and now getting compile errors. Looks like I'm missing something? /usr/lib/mysql/libmysqlclient.a(viossl.o)(.text+0x25): In function `report_errors': : undefined reference to `ERR_get_error_line_data'

[Dovecot] dovecot(pam_unix)[13823]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost
by Dovecot 19 Jul '05

I installed Dovecot on our FC3 sendmail server and get this from our Dallas office ( out of state to me ). dovecot(pam_unix)[13823]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost Only one Dallas user can get mail (pop3 or imap). All local users work fine. I ended upgoing back to UW and all works fine. What should I look for? Thanks

Re: [Dovecot] linux 2.4 vs 2.6 kernel
by Brian Bartholomew 19 Jul '05

19 Jul '05

I can heartily recommend reiserfs on kernel 2.4 for Intel and Sparc. My spam filtering setup currently has 27K files in a quarantine dir, and it works just fine. In a year and a half over 50 machines I've had three corrupted reiserfs filesystems, none of them on production machines, at least one of which I can blame on a bad disk. I would not be surprised to learn they were all bad disks, because the disks are five+ years old. For the last one I moved the bad dir aside where it sat peacefully for a week, and when I fsck'ed it the more aggressive mode of fsck coredumped partway through and it became unaccessable. I then restored it from the tar I had made prior. Brian

[Dovecot] IMAP: Get rid of non-existent folders below INBOX
by André Wendt 19 Jul '05

19 Jul '05

Hi, I am using Debian Sarge w/ dovecot-imapd package 0.99.14-1. Squirrelmail created three folders below INBOX, Drafts/Sent/Trash, that I already had elsewhere. Thus, I deleted them (through SqM). However, both Thunderbird and Squirrelmail still show these folders anyway. When I select them, I keep getting "Mailbox does not exist" errors. I already tried to move all .imap.index* files in .INBOX/ out of the way -- dovecot created new ones but the folders still appear. I am stuck. How can I prevent dovecot from advertising those non-existent folders? Is this an index-structure problem? I'd appreciate any suggestions. Thanks, -- André
