[Dovecot] Authorization client connect failing
by Ryan Hinton 19 Jan '07

19 Jan '07

Hello, and thank you in advance for your valuable time. I am running Dovecot v1.0.rc15 on an OpenBSD 3.9 i386 machine (no time to upgrade yet). I downloaded the source from the dovecot site, compiled and installed without any problem. The server starts up find and runs for a while. After a few hours to a few days, the server stops sending the CAPABILITY statement when a client tries to login. I found a few descriptions of this problem on the web, but no satisfactory resolution. I added some debugging code to the functions in auth-client.c and got the following traces. Included in this email are a successful login attempt, a failed attempt, and a startup trace. I am not a UNIX sockets guru and don't know the dovecot internals well enough to figure out what's wrong. I am happy to add/remove debugging code as requested to help track down the problem, although it may take a few days for the server to hang again. I hope someone can help me figure out the problem so my mail server works reliably! Here is a successful login attempt. Dec 9 10:34:45 myhost dovecot: imap-login: DEBUG:: auth_client_is_connected?

[Dovecot] Connection to server time out when deleting (moving to Trash)
by Anders Lund 19 Jan '07

19 Jan '07

Hi, Running: * Dovecot 1.0 rc15 * Debian Sarge Linux Using Maildir and IMAP over SSL. When trying to delete a lot of mail (> 5000-6000 messages) in some folder, using Mozilla Thunderbird (1.5.0.7) on Ubuntu, I often experience "Connection to server <hostname> timed out." Any suggestions on how to fix this problem? "Empty Trash" seem to work fine, so I guess this is related to moving a lot of mail from one folder to another (Thrash)? - Anders -- Anders Lund <Anders.Lund(a)uninett.no> .~.

[Dovecot] Virtual Users and Local Users Authentication
by craig carriere 19 Jan '07

19 Jan '07

I am using dovecot on a SLES 10 mail server using postfix as the MTA. The original setup used local users and a single domain. I have now configured postfix to send mail to a second virtual domain which is working fine. I am trying to get dovecot to pick up the mail and have been having authentication problems. My local users uses pam and /etc/passwd for login with SSL. I have created a passwd file for the virtual users and have set dovecot to look at the passwd-like file with the path specified. However dovecot complains about the file not being present, which it is and my local users can not login. Probably doing something simple incorrectly, but can not find what fron online searches.

[Dovecot] Migrating from UW-IMAP
by Jay Chandler 19 Jan '07

19 Jan '07

Greetings. I've got a poorly conceived and implemented system I'm trying to migrate off of. Right now we've got 20K accounts or so, in mbox form, under UW-IMAP. Eventually we're going to move to Maildir format, but the first step is to move to Dovecot on one of our imap servers as a proof of concept. In other words, all config changes have to take place on the dovecot side, until I get PHB approval to proceed further. Right now, the inboxes are the user's username, located in /var/mail (an NFS mounted volume). So my inbox would be at /var/mail/chandler. The sub-mailboxes are in the user home directories, just scattered around-- no /mail subdirectory or anything close. So there's a folder called ~chandler/INBOX.Sent, ~chandler/INBOX.Trash, and a ~chandler/Dovecot (for this list). The list of these files is kept in ~chandler/.mailboxlist. I attempted to follow the instructions at http://wiki.dovecot.org/Migration about: You can either rename your .mailboxlist file to .subscriptions for all your users using uw2dovecot.sh <http://wiki.dovecot.org/uw2dovecot.sh>, or change the definition of SUBSCRIPTION_FILE_NAME in /src/lib-storage/subscription-file/subscription-file.c/. In 1.0-test, this value is defined in /src/lib-storage/subscription-fileindex/maildir/maildir-storage.h/ and /src/lib-storage/subscription-fileindex/mbox/maildir-storage.h/. .subscriptions is located inside of the mail directory, whereas it is possible .mailboxlist was outside of it (in user's home directory). However, I built dovecot from ports on FreeBSD 6.2, and the only files that approach this are: wurfel# ls -al total 58 drwxr-xr-x 3 root wheel 512 Jan 16 20:48 . drwxr-xr-x 6 root wheel 1024 Jan 16 20:48 .. drwxr-xr-x 2 root wheel 512 Jan 16 20:48 .deps -rw-r--r-- 1 root wheel 14662 Jan 16 20:48 Makefile -rw-r--r-- 1 root wheel 266 Oct 20 2004 Makefile.am -rw-r--r-- 1 root wheel 14009 Jan 6 23:26 Makefile.in -rw-r--r-- 1 root wheel 4374 Jan 16 20:48 libstorage_subscription_file.a -rw-r--r-- 1 root wheel 6935 Jan 3 15:19 subscription-file.c -rw-r--r-- 1 root wheel 703 Jan 13 2006 subscription-file.h -rw-r--r-- 1 root wheel 4060 Jan 16 20:48 subscription-file.o wurfel# pwd /usr/ports/mail/dovecot/work/dovecot-1.0.rc17/src/lib-storage/subscription-file I took a look at subscription-file.c, but didn't notice where I should change the definition of the file itself-- my code-fu is weak. If someone could lend a hand, I'd be deeply appreciative.

[Dovecot] Bounce vs. Defer
by Jeff Mitchell 19 Jan '07

19 Jan '07

Hello-- I've noticed that with when using deliver, if there is a misconfiguration in my dovecot configuration file, a permissions problem on the maildir, etc., deliver will bounce the message. I'm using Postfix, and at some point used Maildrop, and I know that maildrop (and I believe also Postfix's virtual transport) instead defer the message if there is some kind of fixable problem (like permissions). Then, when the problem is solved, you can flush the queue. Would it be possible to add a defer option to deliver? It makes it difficult to try out new options or different configurations because if you have fairly regular incoming mail, the last thing you want is a ten minute period where 20 messages get bounced... Thanks, Jeff

[Dovecot] dovecot as POP3 proxy
by Alexander Shikoff 19 Jan '07

19 Jan '07

Hello, I am trying to set up dovecot as pop3 proxy. There is net lines in my auth section: passdb passwd-file { args = /usr/local/etc/dovecot/proxy.users } userdb static { args = uid=26 gid=6 } File proxy.users should contain a list of users. Now it looks like test:::::::proxy host=10.10.10.10 and everything is OK. My question is how to change passwd-file in order to match any username? I need something like *:::::::proxy host=10.10.10.10 Thanks in advance! -- Kind Regards, Alexander Shikoff

[Dovecot] FreeBSD, Postfix, Cyrus SASL, Dovecot IMAP, SquirrelMail, Active Directory
by Phil Anslemo 19 Jan '07

19 Jan '07

Here's an update to my configuration. I'm able to use Cyrus SASL to enable SMTP AUTH in PostFix, validate user's mail addresses in Active Directory, and store mail in maildir on FreeBSD. I am currently able to authenticate AD users with Dovecot and LDAP, but I'm getting the following error in the log: Error: IMAP(user@domain): Ambiguous mail location setting, don't know what to do with it: user@domain (try prefixing it with mbox: or maildir:) Error: IMAP(user@doman): Failed to create storage data: user@domain. Error: child xxxxx (imap) returned error 89 I double-checked dovecot.conf, and the mail_location setting is "mail_location = maildir:/usr/data/vmail/%u". I'm not sure what could be happening, but I'm thinking this is the last thing I need to get my configuration to work. Your assistance is greatly appreciated.
