Mailscanner/Spam Assassin supportforMicrosoftIMF/SCLSpamscoring?

[Duncan, Brian M.]

No Christian,  your message did make it yesterday. I was excited that
someone was already doing this..  I read it and figured I would be able
to do what you documented.

Unfortunately, the MS IMF user configurable content filter will ONLY act
on subject or body or both.  NOT message headers.  (From everything I
have read, I even had an Exchange admin here set it up and from looking
at it there is NO capability to act on the presence of a specific
header)

So organizations that tag Spam based on message headers it does not look
like you can get Spam Assassin/Mail Scanner logic to flow through to
Exchange/Outlook junk mail folder.

Yet there is a possible solution, I have sent emails to this company and
am awaiting a reply and an eval of the product.

http://www.smtptracker.com/

Assassin2Exchange filter (SpamAssassin to Exchange Spam Confidence Level
conversion utility) released with SMTPTracker version 2.0. This
stand-alone utility offers custom header conversion from spamassassin
spam level to Exchange 2003 scl value (more complex than current
s-tracker's conversion) and is available free to registered users. If
you feel like this is what you need, send questions and sugestions to
info at smtptracker.com.

They charge 35.00 for an enterprise unlimited license for the product,
or 500 for the source code.  It looks like this might work as an
alternative for Those like me, that do not want subject or body
modifications. 

I know this is the MailScanner list, and this technically is now beyond
MailScanner.  I just wanted to follow up on this incase anyone else was
thinking it would be good to put support for this in MailScanner or Spam
Assassin.

(it looks like the xheader for IMF SCL score is not all that is needed
anyhow, I tested today having mail scanner create the SCL header on
failed Spam messages before hitting Exchange, IMF just ignored the
header and re-processed the messages)

Strange, I tried to send to the list yesterday and it just went *poof*
for some reason.

Here's my experience with IMF/SCL and MailScanner:

I've been using the exchange features to assign a SCL score to any
message that has the tag added by the mailscanner server.
You can set it up so that all of those tagged messages go automatically
to the exchange user's junk email folder. I haven't had any complaints
about it and it allows for easier cleanup of those messages later.

If anyone is interested, check out the following page
http://www.msexchange.org/tutorials/Intelligent-Message-Filter-version-2
-IMF-v2.html

Once you have it enabled, just create a rule in your
MSExchange.UceContentFilter.xml with something similar to:

<?xml version="1.0" encoding="UTF-16"?>
<CustomWeightEntries
xmlns="http://schemas.microsoft.com/2005/CustomWeight">
<CustomWeightEntry Type="SUBJECT" Change="8" Text="*****JUNK
MAIL*****"/> </CustomWeightEntries>

To tag it with any score you've set above your junk level (in the above
example 8)

Cheers,

-Christian

That is good to know, thanks for the research and follow up.
