[Dovecot] strange looking code and userdb errors
by Tony den Haan 13 Jun '08

13 Jun '08

hi, i'm trying to use passdb ldap and userdb prefetch, using the userdb_ prefixes in pass_attrs, and i get: passdb didn't return userdb entries looking at the code at auth/userdb-prefetch.c i see: if (auth_request->userdb_reply == NULL) { if (auth_request->auth->userdbs->next == NULL) { /* no other userdbs */ auth_request_log_error(auth_request, "prefetch", "passdb didn't return userdb entries"); } else { /* more userdbs, they may know the user */ auth_request_log_info(auth_request, "prefetch", "passdb didn't return userdb entries"); } callback(USERDB_RESULT_USER_UNKNOWN, auth_request); return; } is this really correct? if so it migth be a good idea to at least print different errors Tony

[Dovecot] auth issues on centos5 with ldap backend
by Jurvis LaSalle 13 Jun '08

13 Jun '08

Hi, We've had some issues with auth. /var/log/secure is full of 1000s of these lines: Jun 4 19:12:08 khan dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser= rhost=127.0.0.1 user=user123 Users can usually login OK with their ldap credentials, but occasionally logins slow to a crawl if not outright fail, esp people checking mail through Squirrelmail. Things get better after a dovecot restart. Googling around, I thought if we switched the order or disabled the second passdb we had configured for our dovecotadmin account, these failures would go away but that did not happen. Any thoughts or additional info I can provide? Pardon the unusual install prefix. We're trying to keep the source install separated from the ancient dovecot rpm shipped in rhel5. Thanks, Jurvis [root@khan ~]# /etc/dovecot/sbin/dovecot -n # 1.0.13: /etc/dovecot-1.0.13/etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log ssl_cert_file: /etc/pki/dovecot/certs/star.idi.harvard.edu.crt ssl_key_file: /etc/pki/dovecot/private/star.idi.harvard.edu.key login_dir: /etc/dovecot-1.0.13/var/run/dovecot/login login_executable: /etc/dovecot/libexec/dovecot/imap-login mail_location: maildir:/RAID5/mailboxes/%u maildir_stat_dirs: yes maildir_copy_with_hardlinks: yes imap_client_workarounds: outlook-idle delay-newmail auth default: executable: /etc/dovecot/libexec/dovecot/dovecot-auth master_user_separator: * debug: yes debug_passwords: yes passdb: driver: pam args: blocking=yes userdb: driver: passwd args: blocking=yes

[Dovecot] Antispam plugin custom behavior?
by Kyle Wheeler 12 Jun '08

12 Jun '08

Hello, I currently have a setup on my system with what I call "magic folders" to enable spam filter training. Here's how it works: 1. If you have a false-negative, put the spam into the Spam.Report folder 2. If you have a false-positive (which has all kinds of ugly spamassassin protective markup in it), put the message into the Spam.NotSpam folder Currently what happens is that a cron job comes along every five minutes and processes the messages in those folders. In the case of the NotSpam folder, it strips the message of the spamassassin markup, retrains the bayesian net, and redelivers the message (e.g. via deliver). In the case of the Report folder, the message is used to train the bayesian net (among other things) and then deleted. I'd love to be able to trigger these actions when the mail is moved, rather than have a cron job inspecting the mailboxes. I looked into the antispam plugin (http://johannes.sipsolutions.net/Projects/dovecot-antispam) which seems nice but doesn't appear sufficiently generic for my needs. What would really work is if I could get it set up such that putting a message into either of those directories is turned into piping the message to a script of my choosing (a different one for each folder). Does anyone know a good way of getting my own custom behavior in here, or is my cronjob setup probably the best way? ~Kyle -- The optimist thinks this is the best of all possible worlds. The pessimist fears it is true. -- J. Robert Oppenheimer

[Dovecot] quota-rewrite patch & userdb quota overriding
by Alan Premselaar 12 Jun '08

12 Jun '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've spent the past couple of hours trying to figure this out by checking the wiki and googling, but haven't come up with anything that works yet. I just installed dovecot 1.0.14 with the quota-rewrite (1.09) patch and i'm trying to get the quota overridden via a passwd-file type userdb. I had 1.0.13 without the new quota style patched in working but having trouble figuring this out. any help would be appreciated. prior to the quota-rewrite patch (which i installed with the hopes of using quota_warn feature) i was able to put the following line into my passwd-file userdb and it was working: alan:*:1000:1000::/home/alan::userdb_quota=maildir:storeage=2048000:ignore=Sent (which is what I wanted) but now with the new quota definition style, I'm not sure what I need to define the extra fields as. here is dovecot -n: # 1.0.14: /usr/local/etc/dovecot.conf log_path: /var/log/dovecot.log protocols: imap imaps managesieve ssl_cert_file: /etc/pki/tls/certs/dovecot.pem ssl_key_file: /etc/pki/tls/private/dovecot.pem disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(managesieve): no verbose_proctitle: yes mail_location: maildir:~/Maildir mail_debug: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve sieve_storage(default): sieve_storage(imap): sieve_storage(managesieve): ~/sieve sieve(default): sieve(imap): sieve(managesieve): ~/.dovecot.sieve auth default: ~ passdb: ~ driver: pam ~ userdb: ~ driver: passwd-file ~ args: /usr/local/etc/dovecot.passwd ~ userdb: ~ driver: passwd ~ socket: ~ type: listen ~ master: ~ path: /var/run/dovecot/auth-master ~ mode: 384 ~ user: dovecot ~ group: dovecot plugin: ~ quota_rule: *:storage=1G ~ quota_rule2: Trash:storage=100M thanks, alan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkhPd+cACgkQE2gsBSKjZHQNMACghSk7awVX1Aj5HVeo0KjRxyZc lT0AoLJA00SiYiefi2wNrAOt7L6N5eg4 =mA8L -----END PGP SIGNATURE-----

[Dovecot] Wrong message information
by Anders 12 Jun '08

12 Jun '08

We have a few users that every so often get empty data in their message overview. From and subject are empty, and the date is 1-Jan-1970. When opening the message in full view, all things are fine. Also, the data in the actual maildir file is fine. It looks a lot like the issue described here: http://dovecot.org/list/dovecot/2008-March/029282.html The server is Linux, ext3, no NFS, and Dovecot 1.1.rc4. The few clients that have had this problem so far have been Outlook Express. What can be done to debug this? Thanks, Anders.

[Dovecot] Mutually exclusive Exim setup instructions
by Karl Schmidt 12 Jun '08

12 Jun '08

The correct way has to be one or the other: http://wiki.dovecot.org/LDA/Exim are mutually exclusive with http://wiki.dovecot.org/HowTo/DebianStable It appears that exim can either call dovecot's LDA or make the delivery itself. There may be good reasons to do it one way or the other. ---------------------------------------------------------------- Karl Schmidt EMail Karl(a)xtronics.com Transtronics, Inc.

[Dovecot] Dovecot 1.1 rc9 compilation warnings
by Chris Wakelin 11 Jun '08

11 Jun '08

I've tried compiling 1.1.rc9 on everything to hand and I get various compilation warnings (but the compilation finishes). I don't know whether any of them are worth tracking down? I'm guessing most of the differences depend on the default gcc options and a couple of them are probably specific to our setup.
