    I think if you're after a mail relay that does spam filtering, the simpliest solution is actually MTA (postfix, qmail, exim, whatever) + SpamAssassin (and/or DSPAM) + ClamAV + etc, as Bill suggested.

    If you want quarantaine and web access to the quarantaine (and to the whole setup), you should give Maia Mailguard a try and leave Zimbra doing its own job 8)

    Of course, there are commercial closed source solutions doing the same job.

    I am in a similar situation - we have remote offices where all the users are already set up with Outlook and are checking the (old) iMail system via POP. We want to use Zimbra, but don't want to give the remote offices access to the web client (simply not what management wants). Is there a way that Zimbra can be configured to mark, but still forward SPAM e-mail?

    Thanks!

    zmprov mcf zimbraSpamSubjectTag '[SPAM]'
    zmprov mcf zimbraSpamTagPercent 25
    zmprov mcf zimbraSpamKillPercent 100
    zmcontrol stop
    zmcontrol start


    This will tag at a score of 4, never kill (kill at a score of 20, which you'll never see) and add "[SPAM]" to the subject

    -edit - I should clarify: not forward, but deliver to inbox.

    marcmac - I was not sure if those commands are what I should do, or if that was an answer to someone else's question. Thanks!

    Yes, that's in answer to your question. It will let mail get delivered to ythe inbox and tagged as spam rather than remove it.

    ok - cool! Thanks!

    will that do it globally, or can different domains be specified?

    -edit2- the reason why I ask is that some clients do not want ANY e-mail NOT to be delivered. Also - is the 20 score hard-coded, or can that level be raised as well?

    Ok - I ran this, but now the web interface Global Options has the 'Kill Percent' listed as 75 (default value) and the 'Tag Percent' as 100. The headers of the e-mail though, list the 'tagged_above' section as -10 (which is fine, I'd rather have all headers tagged than none). Then the 'required' section as '20'

    I am not sure what this means, or if I am reading things correctly.

    This does not seem to be working properly - nothing is being tagged as spam properly (presumably because the 'required' limit is set to 20).

    Ideally, what we want is for anything over a 4 to have the subject line tagged with spam, but everything to still be delivered to the Inbox. We do not allow the users to access the web interface because management does not allow this, and we do not want to be responsible for false-positives as that opens us up to too many potential legal issues.

    My original post was in error.

    I should have said

    zmprov mcf zimbraSpamSubjectTag '[SPAM]'
    zmprov mcf zimbraSpamTagPercent 25
    zmprov mcf zimbraSpamKillPercent 100

    Sorry for the mistake
