dovecot - Jan 2017 - Is it possible to use sieve when delivering via pipe to the dovecot deliver command ?

Hello,

I am using Exim with this delivery configuration:

virtual_delivery:
  driver = pipe
  command = /usr/lib/dovecot/deliver -d $local_part@$domain  -f
  ...

I have enabled manage-sieve and uploaded a simple sieve script that I
can see on the server.

man page of /usr/lib/dovecot/deliver says it supports sieve.

Mail debug is enabled:

$ dovecot -n | grep debug
mail_debug = yes

Delivering a mail shows only this line in dovecot log:

Jan 21 17:38:51 myserver dovecot: lda(joe at something.com):
msgid=<20170121183537.7313f219 at homenetwork>: saved mail to INBOX

According to page
http://wiki2.dovecot.org/Pigeonhole/Sieve/Troubleshooting#Sieve_Scripts_are_not_Executed
I should have a log saying that the sieve plugin is loaded

Here is the sieve relevant parts of dovecot -n:

# 2.2.13: /etc/dovecot/dovecot.conf
...
plugin {
  sieve = ~/.dovecot.sieve
  sieve_dir = ~/sieve
}
...
protocols = " imap sieve pop3 sieve"
...
protocol lda {
  mail_plugins = " sieve"
}

Is there a requirement to use delivery via service (unix socket) so
that sieve is enabled?

Or is there a configuration thing I forgot ?

Thank you for your help
Thomas

Not really. But I do notice you're executing deliver rather than
dovecot-lda. Usually, one is a symlink to the other though, so it should
not matter. But, still best change that to rule out problems related to
that.

It should at least be showing debug messages from LDA itself. It may be
logging debug messages elsewhere though (`sudo doveadm log find`).

You can also try to execute /usr/lib/dovecot/dovecot-lda manually:

/usr/lib/dovecot/dovecot-lda -olog_path=/dev/stderr -p
/path/to/test/message.eml

This should print all logging to stderr. You may need to add a -d <user>
argument to select an appropriate user (an it may need to be run as
root). Refer to http://wiki2.dovecot.org/LDA for reference.

Regards,

Stephan.

Thank you Stephan,

I found log location with the command you have suggested.

From the log I understood, that I have not Enabled my uploaded sieve
script (by checking the active radio button in my claws-mail sieve
client).

Sieve is now working
