Hi Clinton, I've come across the same problem several times before - Outlook keeps messing up it's list of seen UIDLs. Try using Thunderbird instead. I moved a load of people in our company to Thunderbird because they kept having that problem and it's not happened for them since. As a matter of interest - I've seen both Outlook and Outlook Express do this on dovecot, mercury/32 and Exchange (when using pop3 for pickup).

[Dovecot] Logging and libwrap
by Jesse 01 Nov '04

01 Nov '04

Hi, A few things regarding logging and libwrap.. a) PAM_RHOST patch Back in July, dean gaudet helpfully posted a patch to dovecot PAM_RHOST the remote IP. Is this going to be included in the main dovecot tree? It seems like a worthwhile addition. The more informative and concise the logging the better. See http://www.dovecot.org/list/dovecot/2004-July/004011.html for the original message. b) Better logging Is it possible to get logging of when a client connects and disconnects? I'm very used to seeing this information and it's very useful for debugging user sessions. It's frustrating not being able to easily tell whether a user has opened a connection. Really many of the log messages could be more verbose. For instance, on disconnect, I see imap-login: Disconnected [ip.here] but the username they were logged in as isn't included. It would be nice to have that rather than having to dig back for a login message with the same IP. Heck, even the pid isn't logged. That would be nice too. c) libwrap Any chance of getting libwrap support built into dovecot? Right now I'm running dovecot out of xinetd, so that I can see when tcp connections are opened, and take advantage of tcpwrappers. But this causes the problem that dovecot thinks all connections come from the local host. Correlating logins to IPs gets to be a lot of hassle, with the information divided over so many lines, while needing multiple ways to track which messages from xinetd, dovecot and pam match each other. With some of the minor logging changes (more info on one line, notification of tcp connections), plus libwrap, it'd be much simpler and much more informative. :) Thanks for the great imap server. Just thinking of some improvements. :) --- Jesse <j(a)lumiere.net>

[Dovecot] Test51 compile problems

First of all, thanks for a great product. I've been able to get dovecot up and running with minimum pain. Very nice. Running Fedora Core 2 with postfix using mysql for virtual mailbox config.

[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.

[Dovecot] Maildir unreliability
by Timo Sirainen 27 Oct '04

27 Oct '04

Looks like maildir can't be used very realiably without quite a lot of locking. Writing and scanning the directory would have to be locked, but reading wouldn't (as long as the file hasn't been renamed which would require scanning to find it). So much for "no locks needed".. The problem is that opendir()/readdir() may temporarily not return some files if there has been changes in the directory since the opendir(). That means Dovecot thinks a message is expunged, while in fact it really isn't, and the next scan would usually show it again. Currently when that happens, Dovecot usually prints an error message about it and rebuilds indexes. Of course, in real life clients aren't often bombing the same mailbox with tons of changes in multiple connections, which is usually needed to trigger this. I wrote a test program which tests this: http://dovecot.org/tmp/readdir.c I'd like to hear if you can run it in some system without errors. I tested Linux 2.4 and 2.6 with ext2, ext3, xfs and reiser3, Solaris 8/ufs and OpenBSD 3.5/sparc64. Only OpenBSD passed the test, but I'm not sure if it's only because the computer was so slow and didn't switch between processes hard enough. I'd be especially interested about FreeBSD and various NFS systems. If it actually works properly in some systems, I guess I'll make the extra locking configurable.

Well, it's not maildir issue itself, but maildir more or less relies on readdir() not losing renamed files. I'm not sure what you mean by attribute caching, because it's not just with NFS. I'm sure if you point that out to DJB he just says it's not a real problem, because it doesn't happen hardly ever except with some stress test tools, or mailboxes with _many_ simultaneous users. Or maybe with a heavily loaded server. Or ... In any case, I'd rather make Dovecot resistant to this problem entirely rather than hope that everyone uses maildirs only in optimal conditions.

[Dovecot] dovecot and new mail notification for subfolders in Mail.app
by Alan Schmitt 25 Oct '04

25 Oct '04

Hello, I am using dovecot as an IMAP server to which Mail.app (Apple Mail) connects. However I do not get any notification of new mails in folders other than the inbox, unless I disconnect and reconnect Mail.app or click on the folder with new mail. I'm pretty sure the problem comes from Mail.app. I have searched on Google for how to go around this issue, and have not yet found a solution. If someone here uses Mail.app and dovecot, I'd be really glad to have some advice as to what to do. (by the way, and this is probably related: new folders created in the maildir structure do not get reflected in Mail.app until I disconnect and reconnect). Thanks a lot, Alan Schmitt -- The hacker: someone who figured things out and made something cool happen. .O. ..O OOO

[Dovecot] index files
by Jonathan Salomon 25 Oct '04

25 Oct '04

Hi Timo, I am sorry to bug you about this, but I am a bit confused and I have approx 200 users so I don't want to screw this up. I am using the latest FC2 Dovecot RPM: dovecot-0.99.10.5-0.FC2. I am using NFS to mount the /home dirs on the fileserver from the mailserver with mbox. In the docs you said that I should probably use :INDEX=MEMORY. However I think this really pushes the server to its limits with large mailboxes (I have sometimes loads of 8+!). Also I want to use mailaccounts that are shared by users (to multiple users acces the same mailbox simulateously). If I write the index file to a location on the filesystem, will this improve performance and still work with simultaneous logins? Should I upgrade to version 1.00.something because I read somewhere you rewrote the mbox functions? Thanks again, Jonathan
