[Dovecot] noob - integrating dovecot with postfix
by Mitch Pirtle 09 Nov '04

09 Nov '04

Hi list, Just jumped providers and am now desperately trying to get IMAP running on a new server... But not getting the link between postfix and dovecot working. :-( My two problems are: 1) local mail seems to get into the ~/Maildirs, but not from the outside (this is a postfix issue?) 2) I cannot find information on how to tell postfix to use virtual domains/addresses and then connect dovecot to them (as they are now in non-standard locations and/or formats) I'm sure this is a FAQ, but cannot find an example that would walk me though this. Can someone kindly point me in the right direction? -- Mitch

[Dovecot] Excessive imap-login and pop3-login processes
by Ben Beuchler 08 Nov '04

08 Nov '04

I'm running a Linux mail server with Postfix and Dovecot. I've noticed that the number of "imap-login" processes usually sits around 240, and "pop3-login" usually around 50 or so. The comments in the config file seem to indicate that, with my setup, I shouldn't see more than about 10 of each. Am I misunderstanding the config or is this expected behavior? login_process_per_connection = no login_processes_count = 10 login_max_processes_count = 128 login_max_logging_users = 256 The mail server receives about 1.5 - 3 logins per second and usually has around 75 simultaneous IMAP sessions. There are rarely more than 1 or 2 simultaneous POP3 sessions open. Thanks... -Ben -- Ben Beuchler There is no spoon. insyte(a)emt-p.org -- The Matrix

[Dovecot] dovecot 1.0-test52 build notes
by Mark E. Mallett 08 Nov '04

08 Nov '04

I thought I would try to use 'configure' to lay out the dovecot install a little differently than the default. I prefer all the support files under one tree (e.g. in /usr/local/lib/dovecot-1.0) rather than distributed around the filesystem. And I'd be happiest if all of the support files were just at that top level rather than in subdirectories. e.g.: /usr/local/lib/dovecot-1.0/dovecot.conf /usr/local/lib/dovecot-1.0/imap-login /usr/local/lib/dovecot-1.0/dovecot-auth etc. (I'm happy to have a "doc" subdirectory though.) And ideally I'd have the primary executable installed in a more generic place, but tagged with its version number, like /usr/local/sbin/dovecot-1.0 Note that I'm not suggesting this, just explaining what I am after. So the second to last thing I tried was: --program-suffix=-1.0 \ --bindir=/usr/local/lib/dovecot-1.0 \ --sbindir=/usr/local/lib/dovecot-1.0 \ --libexecdir=/usr/local/lib/dovecot-1.0 \ --sysconfdir=/usr/local/lib/dovecot-1.0 \ --datadir=/usr/local/lib/dovecot-1.0 \ --localstatedir=/usr/local/lib/dovecot-1.0 \ But that didn't really work, for the reasons listed in the "last" try below, plus all of the executables got the "-1.0" suffix, not just the "dovecot" program (not a big surprise..). And the last thing I tried: --bindir=/usr/local/lib/dovecot-1.0 \ --sbindir=/usr/local/lib/dovecot-1.0 \ --libexecdir=/usr/local/lib/dovecot-1.0 \ --sysconfdir=/usr/local/lib/dovecot-1.0 \ --datadir=/usr/local/lib/dovecot-1.0 \ --localstatedir=/usr/local/lib/dovecot-1.0 \ which kinda got me where I wanted, except that if I want a dovecot-1.0 executable in /usr/local/sbin I need to add that by hand, and also that the build process added another subdirectory "dovecot": /usr/local/lib/dovecot-1.0/dovecot/ I can (and did) manually remove that final directory and flatten out the tree, and fortunately you've made it possible to specify in dovecot.conf the paths to all the executables and so forth. But it would be nice to be able to create this desired layout entirely via configure and not have to move things around after the fact. Is that even possible? Obviously, don't spend a lot of time on it.. but if I'm missing an option that would get me where I want, I'd be interested in knowing about it. Oh, and "strings src/master/dovecot | grep /usr/local" gives this: /usr/local/lib/dovecot-1.0/dovecot.conf /usr/local/lib/dovecot/imap /usr/local/lib/dovecot-1.0/dovecot/imap /usr/local/lib/dovecot-1.0/run/dovecot /usr/local/lib/dovecot-1.0/dovecot/dovecot-auth /usr/local/lib/dovecot-1.0/dovecot/imap-login /usr/local/lib/dovecot-1.0/dovecot/pop3-login /usr/local/lib/dovecot-1.0/dovecot/pop3 /usr/local/lib/dovecot/pop3 So it looks like there are a couple of places where the configured paths aren't caught (or so it would seem). Yours, -mm-

[Dovecot] dovecot 1.0-test52 compile notes
by Mark E. Mallett 08 Nov '04

08 Nov '04

Compile issues on an older BSD/OS 4.2 system: src/lib/byteorder.h needs #include <netinet/in.h> to pick up in_addr struct src/lib/byteorder.c no "libgen" here (no basename()). Added it inline, no big deal, but you might want to have configure test for this and provide one if it's missing. Also, on this system there are no types like "uint8_t" and "uint64_t" -- instead there are the u_int8_t and u_int64_t et al types. I added some global typedefs, but I gather this is a somewhat common issue, so you might want to test for these. -mm-

[Dovecot] Runas Question
by Chris L. Franklin 08 Nov '04

08 Nov '04

Okay heres a weird question is there anyways to make dovecot run as root ? Heres why: I'm currently using XMail email server (smtp/pop3/virtual accounts). And I love using it. But it really must run as root. I've tryed all the non-root solutions for it. and really I'd prefer to have it run as root. And I'd like to really use dovecot as (on server with xmail). Currently I've got it running with some sendmail server and a few postfixs But really I'd like to get it working with Xmail. So if anyone has any Ideas or how to get Dovecot to run as root. PS. I know the Idea behind dovecot is security and how it's coded to be able to run using non-root accont. So please I'm really only looking for ways to get dove to run as root. And not new ways of reconfiguring my smtp servers so as they don't need to be run as root. -- Chris L. Franklin --

[Dovecot] Unread mail problem
by Clinton Mills 08 Nov '04

08 Nov '04

Okay, here is the set up. I have Outlook set up to keep mail on the server for 5 days. At some point I started downloading all my mail that was on the server over and over again, even though I already have the mail. The weird thing is that it did not download all the mail, just a few. For example it would download 6 messages, then 18, then 12, etc! After I tried it a few times I had 50 of the same message in Outlook? A small fix, but I do not want to so this ever time If I unclick save on server and then check my mail, it will delete all the mail in my mail box. Then I reclick the leave on server for 5 days and it will work fine! Any idea what is going on? Clinton Hitcents.com Tel: (270) 796-5063 ext 105# Fax: (270) 796-3195 Cell: (270) 996-1122

[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] 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

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.
