MTA Search: Non contiguous ranges?
Hello,
I would like a Mail Transfer Agent recommendation. What's the best
MTA, running on any platform, that will accept two or more thresholds
(non-contiguous weight values) for treating messages as spam?
Something like:
0-1 is ham
2-9 is spam
10 is ham
11-99 is spam
Where 4 paths are possible, instead of the normal 2 (below 10 allow,
above 10 tag) such that the treat-as-ham values are literally in
between the spam values. This can be native or via a plugin.
In order of priority, I'm looking for:
1) Compatibility with SpamAssassin
2) Non contiguous score acceptance
3) Compatibility with multiple AV scanners
4) Ease of use
5) Good logging system
Thanks,
Dan

MTAs don't care about ham or spam, they just deliver messages. I think
you're looking for a milter/third-party MTA integration. Just fyi.

Sendmail with MIMEDefang <www.mimedefang.org> can do that. MIMEDefang
can talk to SpamAssassin and several virus scanners, and you can control
its behavior using Perl. This means you can set up any behavior you want.
As an example, we currently have a three-tiered setup where mail below
the SpamAssassin threshold is allowed through, mail above a higher
threshold is rejected, and mail in the middle is let through but flagged
as spam. It would have no problem defining behavior for additional
score ranges.
MIMEDefang is free and open-source (GPL). The authors also have a
commercial product, Can-It, with additional capabilities and simpler
administration: <www.roaringpenguin.com>

Are there any MTA's that actually make this decision?
It seems to me that what you're really looking for is something like
procmail or a milter which is flexible enough to do what you want. It
might be a little tricky to do in procmail, but I know that you could
easily do something like that in MimeDefang (you'd just be writing perl
code to analyze the score and/or rule profiles).

Exim can do that without any plugin.

Exim can do almost anything you want.

Check!

That's what Exim is best at.

I think so, but I can't guarantee that there is no MTA with better logging
facilities.
