[Dovecot] PostLogin Scripting issue
by Cassidy B. Larson 06 Jan '07

06 Jan '07

Trying out the post-login scripting Timo added recently. Wanting to run a SQL query, as detailed in the example on the Wiki. However, my "USER" env variable is set to "OK" instead of the username. DOVECOT_VERSION=1.0.rc16 RESTRICT_GID_FIRST=127 USER=OK All the other variables (MAIL, HOME, etc) are fine with the correct username. Am I missing something obvious? Thanks, -c

[Dovecot] postfix + dovecot auth problem.
by subscriber＠viliar.net.ru 06 Jan '07

06 Jan '07

Hello All! I use postfx 2.3.5 + dovecot (pop3/imap/lda/auth daemon for postfix) rc15. root@post /etc/postfix# grep dovecot main.cf smtpd_sasl_type = dovecot virtual_transport = dovecot dovecot_destination_recipient_limit = 1 root@post /etc/dovecot# grep password_query dovecot-sql.conf password_query = SELECT mail as user, cryptp as password, CONCAT('/home/vmail/',homedir,'/',maildir,'/') as userdb_home, uid as userdb_uid, gid as userdb_gid, CONCAT('dirsize:/home/vmail/',homedir,'/',maildir,'/',':storage=',quota/1024) as userdb_quota, nice as userdb_nice, hosts as allow_nets FROM users WHERE mail = '%u' and access = 'Y' and %Ls = 'Y'; When I insert allow_nets (and it should be used without userdb_ prefix) into password_query I could not send any more letters. In logs next: Dec 19 11:25:30 post dovecot: auth-worker(default): sql(mail(a)example.com): query: SELECT mail as user, cryptp as password, CONCAT('/home/vmail/',homedir,'/',maildir,'/' ) as userdb_home, uid as userdb_uid, gid as userdb_gid, CONCAT('dirsize:/home/vmail/',homedir,'/',maildir,'/',':storage=',quota/1024) as userdb_quota, nice as userdb_nice , hosts as allow_nets FROM users WHERE mail = 'mail(a)example.com' and access = 'Y' and smtp = 'Y'; Dec 19 11:25:30 post dovecot: auth-worker(default): passdb(mail(a)example.com): allow_nets check failed: Remote IP not known As I understand, postfix does not transfer to dovecot auth daemon rip ( remote ip ). And it is looks like allow_nets it is impossible to use together with dovecot sasl auth in postfix. Do we have any workaround on it?

[Dovecot] Dovecot LDA failure in RC16
by Steven F Siirila 05 Jan '07

05 Jan '07

After upgrading a test server from rc15 to rc16, Postfix was no longer able to deliver mail via Dovecot deliver: Jan 5 11:00:59 testhost postfix/local[8873]: 497282EFE: to=<testuser@testhost>, relay=local, delay=1.2, delays=0.13/0.02/0/1, dsn=5.3.0, status=bounced (Command died with status 89: "/opt/dovecot/libexec/dovecot/deliver -f "$SENDER"") Should "status 89" mean something to me?

[Dovecot] rc15 errors
by Nicolas STRANSKY 05 Jan '07

05 Jan '07

Hi, Since I installed rc15 I'm seing the following errors in logs of a server with several hundreds of pop3 and imap users. All the indexes have been erased and recreated after installation. Dec 21 21:06:46 rouge dovecot: pop3-login: inotify_init() failed: Too many open files The maildir mailboxes are on NFS, but the indexes are local. What should be done to correct this error ? These two error have appeared only once: Dec 22 11:02:07 rouge dovecot: IMAP(xxxxxx): file client.c: line 378 (client_handle_input): assertion failed: (!client->disconnected) Dec 22 11:02:07 rouge dovecot: child 31833 (imap) killed with signal 6 Dec 22 12:43:20 rouge dovecot: IMAP(xxxxxx): free(): invalid pointer 0x5bbbe0!

[Dovecot] Failed proxy auth drops connection for IMAP/POP3 proxy in 1.0-RC15
by Bruce Walter 05 Jan '07

05 Jan '07

Hello, I was seeing an odd behavior in a proxy-only configuration of dovecot. When a user entered an incorrect password in either IMAP or POP3, the Dovecot connection would be immediately dropped, sometimes with the auth failure message, sometimes without (a timing issue). I believe I have tracked down the cause to the code commented out in the attached diff. It appears that the proxy handlers are giving the client the go-ahead to attempt authorization again and then dismantling the proxy session. I believe the correct behavior would be to allow LOGOUT or QUIT to end the session and do the tear-down in client_destroy. The commented code all gets executed (with more error checking) in client_destroy, so there shouldn't be any memory leaks that I can see. Please advise if this seems correct or let me know of a different method of fixing. Thunderbird does 'Bad Things (tm)' when the connection is dropped without an authorization failed message... It doesn't re-prompt for the password and the user appears to have correctly authenticated, but the session just sits and no mail can be retrieved.

[Dovecot] Getting "Can't resolve address no: Name or service not known" error when starting Dovecot
by Francesco Piraneo Giuliano 05 Jan '07

05 Jan '07

Hi gentlemen! After running for six month Dovecot 0.99.14 I decided to upgrade to 1.0rc15. Actually Dovecot is running under Slackware Linux 10.2 and I got the package from http://www.linuxpackages.net. Problems? Yes, one! When I try to startup Dovecot program hung: Fatal: Can't resolve address no: Name or service not known I'm not a Dovecot or IMAP guru and I can't imagine what kind of address number (I think is complaining about the machine's IP address) or "name" or "service" that it doesn't know! I googled for the entire afternoon for someone that meet the same problem but I got no interesting clues... Yesterday I installed also iptables and I thought the two things are related so I disabled iptables but... nothing! Here some valuables (I hope!) informations for the good guys that want to help my desperate soul... Thank you again and I hope everybody enjoy the Christmas holidays... Bye!
