problem with Sieve Duplicate Extension when used together with fileinto

21 Apr 2016

      Hi at all,
I'm trying to figure out a problem with Sieve Duplicate Extension when
used together with fileinto. I use a Dovecot 2.2.23 and Pigeonhole v0.4.13
I have a user (user01) with 3 email addresses (mail01@example.com,
mail02@example.com, user01@example.com); I want to discard duplicate,
and I want to move email in different folder, so I'm using this sieve
script:

require ["fileinto", "duplicate", "imap4flags"];
if duplicate {
discard;
stop;
}
if address :is :all "to" "mail01@example.com" {
fileinto "mail01";
}
if address :is :all "to" "mail02@example.com" {
fileinto "mail02";
}
To make my test, I have a script that send always the same email; this
is an example:

Delivered-To: user01@example.com
Received: from smtp-server.example.com ([192.168.1.214])
by lmtp-server.example.com (Dovecot) with LMTP id
YSaBBU53GFdhbwAAIDyJFw
for user01@example.com; Thu, 21 Apr 2016 08:48:41 +0200
Content-Type: text/plain; charset="us-ascii"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit
Subject: TEST EMAIL
From: myself@example.com
To: mail01@example.com, mail02@example.com, user01@example.com
Date: Thu, 21 Apr 2016 08:48:41 +0200
Message-ID: 20160421064841.26889.86769@kratos.example.com
This is a test email
Please ignore me.
The problem is that duplicate extension doesn't ALWAYS work ; I mean,
one time it works (sieve discard 2 duplicate mails), one time it doesn't
work at all (sieve doesn't discard any mail), another time it works
only for one mail (sieve discards only 1 mail)

As you can see, the message ID of a single sent, is the same, so the
duplicate extension should work. If I replace the 'fileinto' rule with,
for example, a 'setflag' rule:

require ["fileinto", "duplicate", "imap4flags"];
if duplicate  {
discard;
stop;
}
if address :is :all "to" "mail01@example.com" {
setflag "\\seen";
}
if address :is :all "to" "mail02@example.com" {
setflag "\\seen";
}
it works like a charm: for every mail sent, the duplicate extension works.
What is it wrong ? someone has any clue ?
Cheers,
Marco

problem with Sieve Duplicate Extension when used together with fileinto

Marco Giunta

if address :is :all "to" "mail02@example.com" { fileinto "mail02"; }

Please ignore me.

if address :is :all "to" "mail02@example.com" { setflag "\\seen"; }
