I'm wondering if there are any plans to implement any extensions to the Sieve scripting language for mail filters.

In particular, it would be very useful to have RFC 5173 extensions - the Body extension
http://tools.ietf.org/html/rfc5173
Quote:
This document defines a new command for the "Sieve" email filtering language that tests for the occurrence of one or more strings in the body of an email message.


The rules in webmail are very attractive as they trigger without any intervention from a mail client, and are independent of whichever computer checks a user's email, however it's quite limiting that you can't search for text in the body of an email.

Nearly all mail clients offer filters that can filter on the body of an email, but it can be difficult to keep rules in sync between different computers and the rules don't trigger unless a client computer checks the email - so they don't take effect, for example, when someone is checking their email on a mobile device.

Server side rules are much more consistent in the way they process emails, however at the same time are limited on not being able to act on the body of an email.

Hi There!

Actually the spam filter custom rules on the server can now do body content. If you go into the Web admin, Spam filter and then Custom rules. when adding a new rule you can select header or body of the message now.

I hope this helps.

Is the Original Poster referring to just spam rules, or mail processing rules at the client end?

Yes, I'm talking about email filtering in the Kerio Connect Client (i.e., server side rules) for individual users.
I have a user who has a complex set of rules in Mail.app and wishes to migrate them to server side rules so that they trigger irrespective of what device checks his email. Most of the filtering is on From: addresses and subject lines, but there are still a number of rules that need to filter on the message body itself.

Connect is very lacking in that area.

Most likely not endorsed by Kerio, but...
Depending on what the user is trying to do, it might be possible by entering a 'close to it' rule through the Webmail interface, and then editing the .\store\mail\yourdomain.name\username\filter.siv file to change the actual rule. BUT, I don't think Kerio has not implemented all of the test keywords for Sieve Email Filtering, such as the "body" keyword.

When manually editing a rule in webmail, if you use a body test keyword, it doesn't parse... I'm not giving my end users root-level CLI access to the server to fix their rules! Very Happy

Actually, the Old Webmail client would let the user edit the actual script text itself, where the new webmail client no longer offers that ability. But, we still don't have access to the BODY tag.
