Let me preface, I started using MD back in 2002, and ran several mail systems with it. Then in 2012, I moved to google, and forgot all my SA and MD stuff. I am now setting up a personal VM to run my website and email, and will migrate off gmail. Server is FreeBSD with Sendmail.

So I thought I would try to build everything from pkg’s in FreeBSD 11. According to what I read, this is as simple as doing “pkg install mimedefang”

That single pkg includes all the perl module dependencies including SpamAssassin.

Then you rebuild sendmail.cf to include the milter.

So I did all that, and the system appears to sort of be working. The issue is, I don’t think SA is being called or utilized. There is no Spam-Score, and also tried sending some test emails with words that would trigger something (male body parts and drugs). I did run sa-update and sa-compile.

When I send a test email to the server, and look at the header, I see this:

From Gmail account.

And I see this in the servers maillog:

Any ideas?

The log line coming from "mimedefang.pl[3438]" is proof that you have Sendmail configured to consult MD and the following 2 lines from "sm-mta[3566]" prove that MD is telling Sendmail to make changes to the message that can only come from code in the "mimedefang-filter" file. In the default mimedefang-filter in the FreeBSD package, the "Milter delete (noop): header: X-Spam-Score" line is the result of code that runs when the SA hits are below the spam threshold.

You appear to be bad at faking spam :)

One solution is GTUBE: the Generic Test for Unsolicited Bulk Email. The line below, with whitespace removed, should be seen by any spam filter as unequivocal spamsign:

XJS*C4JDBQADN1 .NSBN3*2IDNEN* GTUBE-STANDARD-ANTI-UBE- TEST-EMAIL*C.34X
