by Knut Rauscher 01 Nov '04

01 Nov '04

Hello Timo, we are using dovcot v0.99.11 under Fedora Core 1. We tested following reproducible action with Outlook 2000 SP3, Outlook XP SP3 and Outlook 2003 SP1: folder test with subfolder test1 test test.test1 choose 'move folder' from the context (right-mouse-click) menu of test choose that we want to move folder test into his subfolder test1 (nonsense action, but quite a few employees trying to do that...) Outlook displays error message subscriptions shows correctly: test test1 BUT the directory structure of maildir is .test.test1.test.test1 .test.test1.test.test1.test Is this a mishap of Dovecot or Outlook? Regards, Knut

[Dovecot] dovecot seems to be slow
by Götz Reinicke 01 Nov '04

01 Nov '04

Hi, after the update from wu-imap to dovecot, opening e-mails on the imap server seems slower than with wu-imap. I haven't measured any speed yet, but clicking on a message in a folder takes sometimes a couple of seconds to open the mail. Any ideas or performance tips or information you need?

[Dovecot] Possible Feature request
by Chris L. Franklin 01 Nov '04

01 Nov '04

I've Looked over the list of Auth methods that dovecot can use But i didn't see a option for a custom auth option. Would it be possible to add in a way for dovecot to call a script to check a users login info. have it able to retun the the homedir,gid/uid, and weather or not the password matched. -- Chris L.

[Dovecot] Crash (segfault) while reading folder headers
by Steve Meyers 01 Nov '04

01 Nov '04

Occasionally, while reading the headers of a folder, Dovecot crashes. The visible effect in my mail client is that it will tell me a folder has a new message, but when I click on it, it will take forever to load, and there will be no new messages. When another message comes in to that folder, the folder begins to work again. I generated a core from the latest crash, and the gdb dump is included below. After generating the core file, I removed the .imap.index* files from that folder, and it started working again. I am using Fedora Core 1, with dovecot as an RPM (version dovecot-0.99.10.5-0.FC1). It's a Pentium 4 CPU. Let me know if there is any more information that would help you resolve this. ============================================================== Core was generated by `imap'.

[Dovecot] Filesystem requirements
by Nigel Metheringham 01 Nov '04

01 Nov '04

What are the filesystem requirements for dovecot - for example I see some people are running with atime updates switched off (as I intend to do so myself), so presumably dovecot has no need of an accurate atime implementation. How about directory atime? ctime/mtime etc? I'm intending to run on a linux box using local disk, so am currently considering using reiserfs (3.6) with noatime, nodiratime options since that appeared to work with good performance on the quick benchmark test I tried. I do not have a particularly high opinion of reiserfs reliability, but it normally appears to fail in a all-or-nothing way (ie filesystem unusable) rather than some files going corrupt or missing, so I can work round that with a backup regime.
