[Dovecot] sieve rules processing
Hello list,
My question: is sieve support some kind of "continue" action, to explicit tell server processing rules below current one(if current has triged)?
Situation: I have few rules, which fileinto's to different directories. All is working fine, but if I want redirect all my mail for some period of time to another mailbox, I'm adding rule like this, to be processing first.
if anyof (true) { redirect "koshikov@gmail.com"; keep; }
Mail redirecting, but keep state store messages to INBOX. All I want - to process other rules, which will move message to the right imap directory. This situation also happens with vacation sieve-action. In sieve rfc I didn't find any workaround to that actions.
Maybe someone know how to make sieve working in described way?

I am not exactly sure what you mean. Why are you providing an explicit keep command when you want to sort the message further? I would think the following example script does what you need:
== require "fileinto"; require "copy";
# Temporary rule if true { # Forward a copy of all messages to gmail account redirect :copy "koshikov@gmail.com"; }
# File spam into spam folder and stop further processing if header :contains "X-spam" "yes" { fileinto "Spam"; stop; }
# Mailing list if header :contains "list-id" "ietf-mta-filters.imc.org" { fileinto "Lists.Sieve"; }
# Implicit keep will store message in INBOX if it was not # stored already by the fileinto commands above. The :copy # argument to the redirect command prevents that command # from cancelling the implicit keep action.
I hope this helps you along.

Without keep action - mail just redirected to specified mailbox, but it doesn't stores into my inbox.
== require "fileinto"; require "copy";
# Temporary rule if true { # Forward a copy of all messages to gmail account redirect :copy "koshikov@gmail.com"; }
# File spam into spam folder and stop further processing if header :contains "X-spam" "yes" { fileinto "Spam"; stop; }
# Mailing list if header :contains "list-id" "ietf-mta-filters.imc.org" { fileinto "Lists.Sieve"; }
# Implicit keep will store message in INBOX if it was not # stored already by the fileinto commands above. The :copy # argument to the redirect command prevents that command # from cancelling the implicit keep action.

This is my current rule list:
require ["fileinto","envelope","copy"]; # rule:[redirect] if anyof (true) { redirect :copy "alice@domain.com"; } # rule:[Cron] elsif anyof (header :contains "Subject" "Cron") { fileinto "INBOX/Cron"; }
Here is the message's headers: Return-path: bob@domain.com Envelope-to: koshikov.n@domain.com Delivery-date: Thu, 30 Jul 2009 10:29:04 +0300 Received: from [192.168.1.160] by mail.domain.com with ESMTPSA (TLSv1:AES256-SHA:256) id 1MWQ4W-0007bH-38 (envelope-from bob@domain.com) for koshikov.n@domain.com; Thu, 30 Jul 2009 10:29:04 +0300 Message-ID: 4A714B09.9030704@domain.com Date: Thu, 30 Jul 2009 10:26:01 +0300 From: "bob@domain.com" bob@domain.com User-Agent: Thunderbird 2.0.0.22 (X11/20090605) MIME-Version: 1.0 To: =?UTF-8?B?0JrQvtGI0LjQutC+0LIg0J3QuNC60LjRgtCw?= koshikov.n@domain.com Subject: Cron Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit

But this mail save into INBOX, for user koshikov.n@domain.com, (the second rule is not working), in logs I have: Jul 30 10:29:04 deliver(koshikov.n@domain.com): Info: sieve: msgid=4A714B09.9030704@domain.com: forwarded to alice@domain.com Jul 30 10:29:04 deliver(koshikov.n@domain.com): Info: sieve: msgid=4A714B09.9030704@domain.com: stored mail into mailbox 'INBOX' Jul 30 10:29:04 deliver(alice@domain.com): Info: sieve: msgid=4A714B09.9030704@domain.com: stored mail into mailbox 'INBOX'
So :copy acting for me like "keep". Do you have any ideas, why this might happen ?

You are using a if/elseif/else statement. When the if clause (which is always true) is matched, the stuff in the elsif/else clauses is discarded.
You'll need to use 2 separate if statements to make this work.

Thank you for explanation, Tom. Dividing rule list to two separate statements helped.

Yes, your second rule is an elsif, meaning that it is only executed when the first if-condition is not 'true'. Since that first rule has a forced 'true' result, the second rule is absolutely never executed. You script should be:
require ["fileinto","copy"];
# rule:[redirect] if true { redirect :copy "alice@domain.com"; }
# rule:[Cron] if header :contains "Subject" "Cron" { fileinto "INBOX/Cron"; }
Note that the anyof() commands are only necessary when you have multiple tests per if command. Also, I removed the envelope require, since it is not used.

Thank you, Stephan. Your example rules works like a charm.

Out of interest is the conditional around
if true
{
redirect :copy "alice@domain.com";
}necessary? Does a plain inline
redirect :copy "alice@domain.com";not behave in exactly the same manner?
I'm afraid it's a while since I read RFC 5228 (Sieve) and I was unfamiliar with RFC 3894 (:copy) but on scanning through them I can't see anything to indicate that behaviour should differ inside and outside an "if".
So I suppose my question is does "redirect :copy" have different behaviour based on whether it is inline or inside an "if"?

By the looks of it, this was generated by the sieverules plugin for the RoundCube webmail client. In this case it looks more like a limitation of the script generator, meaning that it doesn't omit the if statement when the rule is unconditional.
Other than that, the if true {...} statement is completely useless and adds nothing to the semantics of the script.
