We recently upgraded to dovecot v1.0.15 (from v1.0.0 + some local fixes), and after this upgrade we've started to get a couple of failures from deliver: Jan 12 20:34:34 smtp1.ulh.mydomain.net deliver(someuser(a)somedomain.net): Raw backtrace: /usr/local/dovecot/libexec/dovecot/deliver(i_syslog_panic_handler+0x1c) [0x45577c] -> /usr/local/dovecot/libexec/dovecot/deliver [0x45537c] -> /usr/local/dovecot/libexec/dovecot/deliver(mail_index_sync_update_index+0x86f) [0x43eb8f] -> /usr/local/dovecot/libexec/dovecot/deliver(mail_index_sync_begin+0x245) [0x43c6e5] -> /usr/local/dovecot/libexec/dovecot/deliver(maildir_sync_index_begin+0x45) [0x4162d5] -> /usr/local/dovecot/libexec/dovecot/deliver(maildir_transaction_save_commit_pre+0x68) [0x41c638] -> /usr/local/dovecot/libexec/dovecot/deliver(maildir_transaction_commit+0x70) [0x417320] -> /usr/local/dovecot-1.0.15/lib/dovecot/lda/lib10_quota_plugin.so [0x2a9557d3a8] -> /usr/local/dovecot/libexec/dovecot/deliver(deliver_save+0x136) [0x410856] -> /usr/local/dovecot/libexec/dovecot/deliver(main+0x1023) [0x411c43] -> /lib64/tls/libc.so.6(__libc_start_main+0xdb) [0x3cbd81c40b] -> /usr/local/dovecot/libexec/dovecot/deliver [0x40ffaa] Jan 12 20:38:53 smtp2.ulh.mydomain.net deliver(quarantine(a)mydomain.net): Raw backtrace: /usr/local/dovecot/libexec/dovecot/deliver(i_syslog_panic_handler+0x1c) [0x45577c] -> /usr/local/dovecot/libexec/dovecot/deliver [0x45537c] -> /usr/local/dovecot/libexec/dovecot/deliver(mail_index_sync_update_index+0x86f) [0x43eb8f] -> /usr/local/dovecot/libexec/dovecot/deliver(mail_index_sync_begin+0x245) [0x43c6e5] -> /usr/local/dovecot/libexec/dovecot/deliver(maildir_sync_index_begin+0x45) [0x4162d5] -> /usr/local/dovecot/libexec/dovecot/deliver [0x416ed5] -> /usr/local/dovecot/libexec/dovecot/deliver(maildir_sync_last_commit+0x4b) [0x4170bb] -> /usr/local/dovecot-1.0.15/lib/dovecot/lda/lib10_quota_plugin.so [0x2a9557d3a8] -> /usr/local/dovecot/libexec/dovecot/deliver(deliver_save+0x136) [0x410856] -> /usr/local/dovecot/libexec/dovecot/deliver(main+0x1023) [0x411c43] -> /lib64/tls/libc.so.6(__libc_start_main+0xdb) [0x322e11c40b] -> /usr/local/dovecot/libexec/dovecot/deliver [0x40ffaa] Jan 13 10:37:59 atmail1.ulh.mydomain.net deliver(quarantine(a)mydomain.net): Raw backtrace: /usr/local/dovecot/libexec/dovecot/deliver(i_syslog_panic_handler+0x1c) [0x45577c] -> /usr/local/dovecot/libexec/dovecot/deliver [0x45537c] -> /usr/local/dovecot/libexec/dovecot/deliver(mail_index_sync_update_index+0x86f) [0x43eb8f] -> /usr/local/dovecot/libexec/dovecot/deliver(mail_index_sync_begin+0x245) [0x43c6e5] -> /usr/local/dovecot/libexec/dovecot/deliver(maildir_sync_index_begin+0x45) [0x4162d5] -> /usr/local/dovecot/libexec/dovecot/deliver(maildir_transaction_save_commit_pre+0x68) [0x41c638] -> /usr/local/dovecot/libexec/dovecot/deliver(maildir_transaction_commit+0x70) [0x417320] -> /usr/local/dovecot-1.0.15/lib/dovecot/lda/lib10_quota_plugin.so [0x2a9557d3a8] -> /usr/local/dovecot/libexec/dovecot/deliver(deliver_save+0x136) [0x410856] -> /usr/local/dovecot/libexec/dovecot/deliver(main+0x1023) [0x411c43] -> /lib64/tls/libc.so.6(__libc_start_main+0xdb) [0x3ac5a1c40b] -> /usr/local/dovecot/libexec/dovecot/deliver [0x40ffaa] Unfortunatley these leads to bounce messages to the sender: Jan 13 10:37:59 atmail1.ulh.mydomain.net postfix/pipe[6320]: BB3337E4E7: to=<quarantine(a)mydomain.net>, relay=dovecot, delay=2.3, delays=0.06/0/0/2.2, dsn=5.3.0, status=bounced (Command died with signal 6: "/usr/local/dovecot/libexec/dovecot/deliver") First, does anybody know if it's possible to change the behaviour here to not bounce, but retry instead ? And, is there anything we should do to debug further what the problem might be ? -jf

[Dovecot] Migration dbmail -> dovecot.
by Андрей Юртайкин 20 Jan '09

Hi i want to migrate from dbmail to dovecot, the main problem is passwords. dbmail uses "md5-hash" wich crypt "111" to "$1$tZNR7pR4$jMuuKWm7ljRyL8iEMfjep.". Tried all dovecot pass schemes thru `dovecotpw` and no one matches. The main question is how to migrate dbmail -> dovecot.

[Dovecot] "userdb didn't return a home directory" with v1.1.7
by Ivars Strazdiņš 20 Jan '09

20 Jan '09

Hi all, I am running Dovecot v1.1.7 in a relatively quiet and calm environment. Suddenly overnight cron job started throwing out errors like: /usr/sbin/dovecot --exec-mail ext /usr/lib/dovecot/expire-tool Error: userdb(user1(a)mail.example) didn't return a home directory Error: userdb(user2(a)mail.example) didn't return a home directory Indeed, running this command produces: ------------------------- $ sudo /usr/sbin/dovecot --exec-mail ext /usr/lib/dovecot/expire-tool --test Error: userdb(user1(a)mail.example) didn't return a home directory Info: User lookup failed: user1(a)mail.example Error: userdb(user2(a)mail.example) didn't return a home directory Info: User lookup failed: user2(a)mail.example ------------------------- Yet these mailboxes are valid, corresponding users can login, send and receive mail. Other mailboxes are OK, too. Where to to start looking? I found that similar error message with v1.1.6 is fixed in v1.1.7, but I am running v.1.1.7 already. Please see dovecot configuration attached. Thank you for your time, Ivars

[Dovecot] checkpassword auth issues
by Tim Traver 20 Jan '09

20 Jan '09

Hi, ok, I'm am developing a new solution that includes dovecot, and will be wanting to use the latest sieve implementation, so I have chosen to start with 1.2 as the base. I had a working install of 1.1.8 installed, and got a checkpassword setup working properly with it to authenticate a user. I used the passdb to call checkpassword, and the prefetch userdb to tell it to use the values that I sent back from the checkpassword script... I compiled and installed 1.2.alpha5, and now my checkpassword does not seem to be working, and I can't figure out why. If I go back and install 1.1.8, it all works again... here is the dovecot -n : [root@mta3 /local/logs]# dovecot -n # 1.2.alpha5: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.0-STABLE i386 log_path: /local/logs/dovecot.errors protocols: imap imaps pop3 pop3s 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(pop3): /usr/local/libexec/dovecot/pop3-login verbose_proctitle: yes first_valid_uid: 100 mail_uid: 100 mail_gid: 100 mail_location: maildir:%h/Maildir mail_debug: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: username_translation: %@ username_format: %Lu verbose: yes debug: yes debug_passwords: yes passdb: driver: checkpassword args: /bin/checkpassword userdb: driver: prefetch and here is a snip of the logs that I get when trying to log in : dovecot: Jan 19 11:37:47 Info: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=209.132.1.203 rip=209.132.9.162 lport=993 rport=1053 dovecot: Jan 19 11:37:47 Info: auth(default): client out: CONT 1 dovecot: Jan 19 11:37:47 Info: auth(default): client in: CONT 1 AHRpbUBtdGEzLnNjYWxlZHN5c3RlbXMuY29tAENvbGRTdW4x dovecot: Jan 19 11:37:47 Info: auth(default): checkpassword(tim(a)mta3.scaledsystems.com,209.132.9.162): execute: /bin/checkpassword /usr/local/libexec/dovecot/checkpassword-reply dovecot: Jan 19 11:37:47 Info: auth(default): checkpassword(tim(a)mta3.scaledsystems.com,209.132.9.162): Received input: user=tim(a)mta3.scaledsystems.com userdb_home=/home/mailboxes/data/30/tim(a)mta3.scaledsystems.com userdb_uid=100 userdb_gid=100 dovecot: Jan 19 11:37:47 Info: auth(default): checkpassword(tim(a)mta3.scaledsystems.com,209.132.9.162): Received no input dovecot: Jan 19 11:37:47 Info: auth(default): checkpassword(tim(a)mta3.scaledsystems.com,209.132.9.162): exit_status=2 dovecot: Jan 19 11:37:47 Error: auth(default): checkpassword(tim(a)mta3.scaledsystems.com,209.132.9.162): Child 43345 exited with status 2 As you can see, the checkpassword routine is indeed sending outthe userdb_home variable as well as the other necessary variables. Is it possible that checks for the return code from calling the checkpassword script have changed between the versions??? I currently exit the checkpassword script with _exit(0); to make the status 0 when it is successful, and I also set the AUTHORIZED environment variable to "2" as told... wierd thing is that it works in 1.1.8, but not in 1.2 Thanks, Tim.

[Dovecot] Reject message if user is over quota. 2/3 solution for Postfix w/ PostgreSQL
by Pascal Volk 19 Jan '09

19 Jan '09

Hi, according to the both discussions in the last few days I've tried to find a solution for Postfix with a PostgreSQL back-end. Its working nice for regular recipient addresses like user(a)example.com and addresses with an extension like user+foo(a)example.com. Alias addresses are currently ignored. * An alias may expand into multiple destinations. If one of this destinations is over quota Postfix will expose the destination address from the alias * An alias address may point to an external destination. * Aliases, with just one internal destination maybe simple to expand (homework ;-)) Maybe someone of you would provide ideas for handling alias addresses. The procedure is designed for global quota settings. If one of you is using quota settings per user, you have to modify the procedure. Integrating in main.cf: smtpd_recipient_restrictions = ... reject_unlisted_recipient check_recipient_access pgsql:/etc/postfix/virtual_global_quota_check.cf ... virtual_global_quota_check.cf: # The hosts that Postfix will try to connect to hosts = localhost # The user name and password to log into the pgsql server. user = $Your_Postfix_database_user password = $PASSWORD # The database name on the servers. dbname = mailsys # The query query = SELECT postfix_global_quota_check('%u', '%d', 10485760, 1000) # quota limit in bytes ----------------------------^ # quota limit in messages -----------------------------------^ SQL: CREATE OR REPLACE FUNCTION postfix_global_quota_check( IN localpart varchar, IN the_domain varchar, IN q_stor bigint, IN q_msgs bigint) RETURNS TEXT AS $$ DECLARE result text := 'DUNNO'; -- remove extenstion from localpart (user+foo -> user) lpart varchar := (SELECT regexp_replace(localpart, E'\\+.*$', '')); -- XXX how to handle alias addresses? -- stop here if the destination is an external address -- how to handle aliases with multiple destinations??? address varchar := lpart||'@'||the_domain; storage bigint := (SELECT current FROM quota WHERE username = address AND path = 'quota/storage'); messages bigint := (SELECT current FROM quota WHERE username = address AND path = 'quota/messages'); BEGIN --RAISE NOTICE 'users storage: % bytes', storage; --RAISE NOTICE 'users message count: %', messages; IF storage >= q_stor THEN result := '552 5.2.2 Quota exceeded (mailbox for user is full)'; ELSE IF messages >= q_msgs THEN result := '552 5.2.2 Quota exceeded (mailbox for user is full)'; END IF; END IF; RETURN result; END; $$ LANGUAGE plpgsql STABLE RETURNS NULL ON NULL INPUT EXTERNAL SECURITY INVOKER; GRANT SELECT ON quota TO $Your_Postfix_database_user; Regards, Pascal -- Ubuntu is an ancient African word meaning “I can’t install Debian.” -- unknown

So I don't know why the dovecot-uidlist is incorrect. Thanks for comments... STEPHAN
