How to use Sieve with VExim?

[Michael Richter]

Hi,

how can I use Sieve filters with VExim? I couldn't find any documentation about this. Does someone already use this configuration?

Greetings

Hi Michael,

I use a pipe to pass all incoming mails to dovecot where all sieve
filters are implemented (can be configured via roundcube). The pipe
command is:
| /usr/lib/dovecot/dovecot-lda -d us...@domain.com

In the future we want to bring LMTP transports to dovecot into our exim
configuration:

Hi Udera,

thanks for your reply. So you replace mail delivery by Dovecot, right? So I'd need to configure Dovecot LDA too with correct virtual pathes, mysql, etc., right? Sounds like a bunch of work. Where did you put this pipe command?

I believe much of that is in the pull request Udera linked to, and in
our existing documentation on Dovecot
(https://github.com/vexim/vexim2/wiki/Server-configuration:-Dovecot) .

If you prefer processing Sieve filters directly in Exim, you're very
welcome to share whatever recipe you come up with here or in the wiki,
and/or to make a pull request. Exim does seem to support Sieve, but the
manual (a.k.a. Exim specification) doesn't go into much detail when
talking about filtering, at least I haven't noticed any examples we
could use.

Hi Rimas,

I've got a mail with some tips on how to configure it. And I got it working now with Dovecot LDA. On Debian Jessie with Exim 4.88 (self compiled using OpenSSL instead of GnuTLS), VExim 2.2.1 and Dovecot as IMAP server I did something like this:

- apt-get install dovecot-managesieved

- added a transport rule to exim4.conf:

dovecot_virtual_delivery:

  driver = pipe

  return_output

  command = /usr/lib/dovecot/dovecot-lda -d $local_part@$domain -f $sender_address

  message_prefix =

  message_suffix =

  delivery_date_add

  envelope_to_add

  return_path_add

  log_output

  user = 90

  group = 90

  temp_errors = 64 : 69 : 70: 71 : 72 : 73 : 74 : 75 : 78

- activated this transport in router virtual_domains:

file_transport = dovecot_virtual_delivery

- changed Dovecots user lookup via MySQL in dovecot-sql.conf:

user_query = \

    select smtp as home, users.uid, users.gid \

    from users,domains \

    where localpart = '%n' \

    and domain = '%d' \

    and users.domain_id = domains.domain_id

- activated Sieve in 20-managesieve.conf

- activated Sieve in 15-lda.conf:

mail_plugins = $mail_plugins sieve

- granted permission to the userdb in 10-master.conf:

mode = 0777

- reloaded Exim and Dovecot

Maybe I've forgotten some part but something like this should do it.

Greetings

Michael
