I see this get posted to the list periodically, but I've tried all
the solutions I've seen and think I've correctly implemented them.
I've got mimedefang-2.56 driving Mail-SpamAssassin-3.1.0, clamav-0.88,
razor-agents-2.77. It is running on a RHEL linux box, but that probably
doesn't matter too much since I've recompiled perl (-5.8.8) and added in
all the associated modules, rather than use the aged version RedHat ships.
In short:
I've added $SALocalTestsOnly = 0
I know both sa-mimedefang.cf and mimedefang-filter are being used
Standalone tests from "defang" user show razor checks
I see no evidence of razor checks added to headers/reports
I don't see the .log file in ~defang/.razor getting updated (by MD)
When I check it out by hand, I see results:
[/opt/mx/bin/spamassassin -t -D < /tmp/sample.msg 2>&1 | grep -i razor]

Configuration details, for those that have read this far.
I tracked down init.pre and made sure I had it set up:

The spamassassin .cf file is pretty stock, perhaps with extra bits in
it as I've tried to enable things with or without success:

I know it is using this .cf because of the report difference, at the
very least.
Idle note, I can't guarantee that bayes is working at this point
in time. Turned it on not too long ago, or tried to, probably doesn't
have enough ham samples yet.
The mimedefang-filter has had a bit more customization done to it. There are
cosmetic
textual changes. Important thing being that the "$SALocalTestsOnly = 0;" is in
there
(and I know that kicks in because I see the blackhole checks in the spam
reports).
