Hi, I read a lot of howto's and I got problems with LDAP and Dovecot to work together. I'm using: Gentoo Linux 2008.0 hardened Dovecot 1.1.7 Kernel 2.6.26 OpenLDAP 2.3.43 My dovecot-ldap.conf is: uris = ldaps://auth.mydomain.com:636 auth_bind = yes auth_bind_userdn = uid=%u,ou=People,dc=mydomain,dc=com ldap_version = 3 base = ou=People,dc=mydomain,dc=com deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) default_pass_scheme = CRYPT I also tried default_pass_scheme = MD5-CRYPT In the logs I find smething like this: Feb 16 12:20:49 mail dovecot: Dovecot v1.1.7 starting up Feb 16 12:20:50 mail dovecot: auth(default): new auth connection: pid=30582 Feb 16 12:20:50 mail dovecot: auth(default): new auth connection: pid=30583 Feb 16 12:20:50 mail dovecot: auth(default): new auth connection: pid=30584 Feb 16 12:20:53 mail dovecot: auth(default): new auth connection: pid=30585 Feb 16 12:20:58 mail dovecot: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=172.30.0.10 rip=172.30.0.254 lport=993 rport=51269 Feb 16 12:20:58 mail dovecot: auth(default): client out: CONT 1 Feb 16 12:20:58 mail dovecot: auth(default): client in: CONT 1 AGd1ZW50aGVyADE*********= Feb 16 12:20:58 mail dovecot: auth(default): ldap(guenther,172.30.0.254): invalid credentials Feb 16 12:21:00 mail dovecot: auth(default): client out: FAIL 1 user=guenther Feb 16 12:21:00 mail dovecot: auth(default): client in: AUTH 2 PLAIN service=imap secured lip=172.30.0.10 rip=172.30.0.254 lport=993 rport=51269 resp=AGd1ZW50aGVyADE*********= Feb 16 12:21:00 mail dovecot: auth(default): ldap(guenther,172.30.0.254): invalid credentials Feb 16 12:21:02 mail dovecot: auth(default): client out: FAIL 2 user=guenther It seems dovecot ignores the CRYPT password scheme.

[Dovecot] quota warning issue

[Dovecot] unkillable imap process(es) with high CPU-usage
by Arno Wald 15 Feb '09

15 Feb '09

Hello, I am having a problem with my dovecot-daemon. It is forking one or more (I saw up to perhaps 8 of them) imap processes under my user name. These processes are consuming a lot of CPU time and are not killable: > PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND > 8616 arno 20 0 2900 1600 1204 R 98 0.2 1196:38 imap Stopping dovecot does not quit these processes. Killing them (even "kill -9" as root) is not possible. The only solution to get rid of them is to reboot. I have found a mailing list post of one who seemed to have the same problem. He solved it by upgrading to version 1.1. But in my case this did not help. Is this a known problem? What could I check or do? My system: very up to date debian/sid (sidux) kernel 2.6.27-8.slh.1-sidux-686 CPU: Intel(R) Core(TM)2 CPU 4300 @ 1.80GHz Filesystem: ext3fs tried dovecot from sid: 1:1.0.15-2.3 tried dovecot from experimental: 1:1.1.2-3 My dovecot.conf is the original debian configuration with only one line changed into: protocols = imaps # dovecot -n # 1.1.2: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail auth default: passdb: driver: pam userdb: driver: passwd I am using dovecot locally on my system with me as the only user. As client I am using thunderbird alias icedove 2.0.0.17-1. Icedove retrieves the Mails from another imap server and sorts them into Maildir-folders in dovecot. I do not know when the imap-process are going mad. It happens after the system (and the mail-client) is up for a while. Do you need more information? Thanks, Arno

[Dovecot] great disappearing email mystery
by dhottinger＠harrisonburg.k12.va.us 14 Feb '09

14 Feb '09

Have there been any issues with dovecot and using outlook express (imap) as an email client? I have had a couple of users come up with random missing emails. Im trying to figure out if it is user error, or something wacky in my mailserver. I cant find anything telling in maillog files or my messages. Dovecot version is 1.0.3. Its ok to reply to me, I get list messages digest. thanks, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools "Everything should be made as simple as possible, but not simpler." -- Albert Einstein "The hottest places in Hell are reserved for those who, in times of moral crisis, preserved their neutrality." -- Dante

We are having the same problem. It's not a problem with imap, only with pop3. We're using deliver as the MDA. We're also using flock() locking for the mbox: is that what everyone else is using as well? Migrating our servers to maildir globally is also not an option for us. In some cases, even convincing customers to use IMAP isn't going to work. One problem which might be making this worse than it needs to be, is the fact that mbox_lock_flock in mbox-lock.c is not using a blocking flock(); instead, it's polling for a non-blocking lock. This technique can cause lock starvation, if another process is dropping the lock and picking it back up again frequently: other processes will only see the lock as being available if they happen to poll for the lock at just the right instant. A better technique to use here, if it's adequately cross-platform, would be to set an alarm() for the max_wait_time, and use a blocking flock(). If the alarm times out and you don't have a lock, it's a timeout. In the meantime, you're guaranteed to eventually get the lock, if it is dropped. That said: I'm not sure whether this will solve our problem in practice. Why doesn't this happen with imap? Why can't we make pop3 do what imap does? Even if it's inefficient, it's better than hanging all incoming mail delivery while deliver eats up our local concurrency limits. Thanks! Alan Ferrency pair Networks, Inc. alan(a)pair.com

[Dovecot] Smooth mailbox to maildir migration
by Luciano Mannucci 14 Feb '09

14 Feb '09

Hi all, I have a postfix+procmail+dovecot installation, now running basicaly on pop3 hence mailbox format, with few thousand users and less than twenty gigabytes mail. I need to move all of them to maildir, to take advantage of IMAP subfolders that do not work with mbox format (so I'm told :). Of course I cannot safely stop the service for more than a bunch of seconds... What I'm about to do: create a second dovecot instance to cope with imap client configured for maildir (and possibly pop3 on another port for those using both), which means a dovecot launched with -c /path/to/alternate.conf and a new /etc/init.d/dovecot2-theRevenge having the proper -i option given to startproc in order to make it ignore the other instance. for each user: convert the mailbox with some sort of mb2mb (which is the better one?) create a .procmailrc with a proper DEFAULT= bearing the magic trailing slash indicating maildir to procmail for each converted user. And I'm done... Have I forgotten something? Is there a better way? Any one else tryed such a thing? Cheers to all, luciano. -- /"\ /Via A.
