Mailarchiva And Spam

[freedomics]

I'm using Zimbra along with Mailarchiva to archive all mail at our small business. I'm very happy with both Zimbra and Mailarchiva.

However, there is one significant issue. Everything is archived, including spam and other inbound mail that will eventually be rejected by Zimbra. This fills my archive with junk.

Mailarchiva integrates with Zimbra by adding the following declaration to Zimbra's Postfix main.cf file.

  smtpd_milters = inet:127.0.0.1:8092

With this configuration, all arriving mail is sent to Mailarchiva (port 8092) BEFORE it is processed by amavisd, etc.

Does anyone know how to configure Zimbra/Postfix so that a copy is sent to local port 8092 AFTER the mail has been checked for viruses, spam, etc?

Is that what you really want ? what happens if you get some FPs as they will not be archived and will not reflect a true message stream.

If it never hits my user's mail boxes, or it wasn't sent from my users, then I don't want to archive it.

This is what I want, yes. I don't want to see the 90%+ spam in my archives. Is there any update to this question?

Has MailArchiva been asked how to do it ?

Has this been solved? I would really like to know the solution as well.

I'm still in contact with both MailArchiva Support and Zimbra support... so far nothing yet. Here are the details: ZimbraIntegration < Main < MailArchiva Knowledge Base. Method 1 should work for Zimbra NE customers, but I'm having some trouble with my MailArchiva server, so I'm not sure if it's what I'm looking for just yet.

I've accomplished this by creating a no-archive rule in Mailarchiva for subject contains "[SPAM]" and running ASSP on another server. ASSP is a much better solution to spam anyway... I can followup with tips on getting ASSP running if need be.

I have setup a tempfail milter on the Zimbra server within Postfix for Mailarchiva. I'm guessing you're catching the e-mail *after* AV/AS is done? So far I can't figure out how to get the mail to Mailarchiva after AV/AS.

Yes, in Zimbra I have setup the main.cf to tempfail milter to my external ASSP/Mailarchiva server.

Here's my rough setup...

Inbound:
internet -> ASSP -> Zimbra -> Mailarchiva via postfix milter
Outbound:
Zimbra -> Mailarchiva -> external SMTP [ASSP] -> Sendmail relay (on same machine as ASSP)

As ASSP inserts "[SPAM]" as a preamble to the subject line on emails marked as spam, Zimbra routes those to the Junk folder automatically and Mailarchiva does not archive if any subject contains "[SPAM]".

It's working wonderfully with low load overhead on either server.
