[Dovecot] problem with dovecot and sieve
Hi
We've been using dovecot with great success so far. We are trying to add sieve support for our users. We enabled managesieve and users can define rules from the webmail (roundcube) with sieverules plugin for roundcube.
Everything goes ok, but here's a problem I couldn't figure yet.
When I define a redirect rule, the mail is forwarded but a local copy is stored too. Weird thing is that the logs say redirecting failed but the mail gets forwarded. Let me show you some of this (personal data masked):
cat .dovecot.sieve
Generated by Roundcube Webmail SieveRules Plugin
rule:[teste]
if anyof (true) { redirect "xxxxx@xxxxxxxxx"; }
And the log from the user's sieve log
sieve: info: started log at Jun 15 18:05:49. error: msgid=<BANLkTik1OzJEreF0qW000OvFpkaR7nOhCQ@mail.gmail.com>: failed to redirect message to <xxxxxx@xxxxxxx> (refer to server log for more information).
syslog:
Jun 16 11:40:26 mailstore5 dovecot: lmtp(8458, xxxxxxx@xxxxxx.com): Error: /eMhMNoV+k0KIQAAmtbU9A: sieve: execution of script /var/maildir++/99/xxxxxx@xxxxxxxx/.dovecot.sieve failed, but implicit keep was successful (user logfile /var/maildir++/99/xxxxxx@xxxxx.com/.dovecot.sieve.log may reveal additional details)
And gets redirected anyway Jun 16 11:40:26 mailstore5 postfix/smtp[13041]: CB4D1C79FE: to=<xxxx@xxxxxxx>, delay=0.12, delays=0.02/0/0.01/0.08, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as E24FAB0880)
There's no explicit keep anywhere in the sieve rule, nor a global rule, so Im confused, the email should be forwarded only. The error message confuses me too, as it says failed but the mail gets through.

Your help is appreciated. Thanks! Javier
Maybe it is useful to know, that vacation does the same thing, an error in the logs but the response arrives to the sender.
Log file also show some error with waitpid()
Jun 16 13:18:27 mailstore5 dovecot: lmtp(8460, xxxx@xxxxxxx.com): Error: waitpid() failed: No child processes Jun 16 13:18:27 mailstore5 dovecot: lmtp(8460, xxxxxx@xxxxxx.com): Error: +F/dFJQm+k0MIQAAmtbU9A: sieve: msgid=<BANLkTin7b5ucfhZmZfqpuuP4TyGwyo9cAg@mail.gmail.com>: failed to send vacation response to <xxxxxx@gmail.com> (refer to server log for more information) Jun 16 13:18:27 mailstore5 dovecot: lmtp(8460, xxxxxx@xxxxxx.com): +F/dFJQm+k0MIQAAmtbU9A: sieve: msgid=<BANLkTin7b5ucfhZmZfqpuuP4TyGwyo9cAg@mail.gmail.com>: sent vacation response to <xxxxxxx@gmail.com>

First thing to notice is that your Dovecot is relatively old, so this problem may be fixed already. Also, recent Dovecot (v2.0) versions support sending messages directly to an SMTP (smart)host instead of using the sendmail binary.
Looks like your sendmail binary terminates inappropriately (or Dovecot thinks it does). Can you successfully send mail from the command line using the sendmail tool?
Regards,
Stephan.
Thanks for the response. I'll try updating dovecot to latest version but this will take me some time, so other options are welcome. It seems like submission_host is from v2.0.10+ and I have 2.0.9 :(
Sending mail with
echo "test" | sendmail xxxx@xxxx.com
works fine. Thanks Javier

No other hint? Only option is to upgrade to latest?
Thanks Javier

Upgrade is an option, just want to know how many I have. But, as being a medium sized mail system, I have to take little steps.
Thanks Javier

or backport the needed things from later sources, its GPL v2 remember ? :)

gives invalid mailheaders, and sieve fails
cat testmail
From: "testmail" <testmail@example.net> To: "abuse" <abuse@example.com> Subject: testmail <empty line> testmail
fire it to seive
sendmail -f testmail abuse <testmail
now its syntax is correct, but i have long time forgothen to add Date: :=)

This is the main problem. It just shouldn't be happening. You could try stracing an lmtp process while it sends a mail, and see if there are two waitpid() calls or of the first one is giving this error. If there is only this one waitpid() call this would seem like a kernel problem.
(Easy way to strace: 1) connect to lmtp socket & quit, 2) strace -p <lmtp pid>, 3) send a mail)

I think this fixes the bug: http://hg.dovecot.org/dovecot-2.0/rev/748b0fd169d1
Of course, since you can't upgrade that's not very helpful.. You could try to figure out why your sendmail binary is forking and not make it do that..
I'll be planning on upgrade soon then, if that cures the problem (ie: i will use submission_host instead of sendmail binary)
Another (maybe) unrelated question. It is possible to add extra parameters so the connection made to submission_host uses user's credentials ? (for authenticated smtp) Or I'm asking something ridiculous?
Thanks Timo, Thanks list.

No possibility to do SMTP AUTH. Way too much trouble, at least for now.
