[Dovecot] Automatic mail script?
by Andreas Andersson 08 Jan '07

08 Jan '07

Hello! I am setting up a Dovecot mailserver for around 2000 people with: sendmail + dovecot + squirrelmail + spamassassin and some plugins. I have the Imap quota working in mboxes with this quota commands: plugin { # 10MB quota limit quota = dirsize:storage=10240 } It worked good in Squirrelmail, but the person that only use some imap program (outlook, eudora) don't get the info when theirs account will be full of mail. So can someone give me a good script for a automatic mail. I want to send a mail to a user when they are nearly exceeded their limits, so they can start cleaning theirs account. Are this possible or how should I solve this problem? /Andreas

[Dovecot] unable to read mail - file istream-raw-mbox.c: line 499...
by Chris H. 08 Jan '07

08 Jan '07

Greetings all, I (nor anyone else) am suddely unable to read mail. Dovecot dumps the following in it's log: # BEGIN LOG ENTRIES # dovecot: Jan 07 18:15:52 Info: imap-login: Login: user=<username>, method=PLAIN, rip=::1, lip=::1, TLS dovecot: Jan 07 18:15:52 Error: IMAP(username): file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) dovecot: Jan 07 18:15:52 Error: child 1584 (imap) killed with signal 6 # END LOG ENTRIES # NOTE: 'username' represents the users name at that time. The users subscribed to folders all show up. But no mail is visable. Dovecot is leaving username.lock files in /var/mail as well. It doesn't do this on my other servers running dovecot. They are using older versions of dovecot tho. Does anyone know what might be causing these problems? Relavent info follows: Dovecot version: 1.0.r15 OS: freebsd-5.5 Thank you for all your time and consideration. -- panic: kernel trap (ignored) ----------------------------------------------------------------- FreeBSD 5.4-RELEASE-p12 (SMP - 900x2) Tue Mar 7 19:37:23 PST 2006 /////////////////////////////////////////////////////////////////

[Dovecot] trouble debugging
by Aaron Solochek 07 Jan '07

07 Jan '07

I want to switch away from bincimap, and I am having some trouble getting dovecot up and running. Something isn't working (I suspect it's a permissions problem) but the logs aren't really telling me anything interesting. I can authenticate and get a list of folders, but when I try to select a folder, I get the "Internal error" message that tells me to check the server logs. The server log shows: Jan 5 19:43:42 sausage dovecot: imap-login: Login: user=<aarons>, method=plain, rip=XXX, lip=XXX, TLS Jan 5 19:43:43 sausage dovecot: IMAP(aarons): Effective uid=1000, gid=1000 Jan 5 19:43:43 sausage dovecot: IMAP(aarons): Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, subscriptions=no Jan 5 19:43:43 sausage dovecot: IMAP(aarons): maildir: data=/XXX/aarons/Maildir Jan 5 19:43:43 sausage dovecot: IMAP(aarons): maildir: root=/XXX/aarons/Maildir, index=/XXX/aarons/Maildir, control=, inbox= How can I get better debugging info? I've tried all the debugging options in dovecot.conf. Thank you. -Aaron

[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?
