Custom Filters

[jefft@iri.columbia.edu]

Hello everyone,

I've searched a bit through the wiki, the forums, and the documentation and cannot find the answer. How do I implement custom email filters with more functionality than the web filter rules support.

For example, I used to have a procmail filter that I used to sort incoming mail by host. I could extract the host with a regexp, then file the email into the appropriate folder. Is there a command-line interface/API for the filtering mechanism? Is there a more powerful way to filter messages than the default web interface? Sieve, Procmail, anything?

Thanks,

Seive is the technology that underlies the mail filter rules. I don't know if it's possible to edit the Seive rules easily, but you might be able to create the rule with the Zimlet.

sieve - you can even convert from procmail:/forums/users/7239-any-way-add-message-filters-command-line.html

very simply it's kinda like:
zmprov modifyAccount user@domain.com zimbraMailSieveScript 'require ["fileinto", "reject", "tag", "flag"]

or there's always:
zmmailbox -z -m user@domain.com addFilterRule "tag special" active any header "subject" contains "special" tag "special" stop
-this should also add it into the user's list of rules to manage from the web interface

Thanks, that's what I was looking for. I was able to add a rule through zmprov, but I ended up losing my next message that it would have matched. Where can I trace the filters? They don't seem to show up in /var/log/zimbra.log.

Also, which takes precedence, zmmailbox or zimbraMailSieveScript ?

Thanks again for your help on this.

As I learn zimbra more, I think I can ask better questions

I have learned a little about Sieve, and was wondering if Zimbra sieve supports the variables extension?

And even better - does anyone have any examples??

Also, my last question was never addressed as to which rules take precedence: the zmmailbox filters or the zimbraMailSieveScript ?

Thanks to anyone who can answer this!

They are the same thing, zmmailbox is just a tool for creating the filters for a mailbox.

Why don't I see anything when I look at the zimbraMailSieveScript variable:
# zmprov ga xxxx@iri.columbia.edu | grep zimbraMailSieveScript
zimbraMailSieveScript: require ["fileinto", "reject", "tag", "flag"];

I can see all my filters using the command:
# zmmailbox -z -m xxxx@iri.columbia.edu gfrl

If I use the zimbraMailSieveScript, will it overwrite all my rules?

zimbraMailSieveScript: require ["fileinto", "reject", "tag", "flag"];

It's because that command will only search fro the line containing zimbraMailSieveScript Use that command without the grep to see all the filters.

With zmprov, yes it will.

grep - duh! That makes a lot of sense

Thanks!

The only thing left that I want to know is if Zimbra supports the sieve variables extension?

I know this is an extremely old thread, but I'm needing to know the same thing. I need to make a sieve script that will take a string from the subject of an email and throw that into a part of the To: field for a redirect. Anybody know?
