I'm well aware that mailman has features beyond what I need and use.  As
there was a chance it could do something magical for cases like this, I
thought I'd ask :-)

As you say, not scalable :-(

My mail handling environment is composed of postfix, procmail,
bogofilter, and mailman.  All incoming messages are _supposed_ to be
processed by bogofilter, which adds a spam/ham tag to the message
header.  Messages to "mydomain.com" have the tags, but messages to
"mylists.org" do not (as confirmed by looking at *.pck in held-msgs).
Can you point me towards a FAQ, HOWTO, or other document which might
shed light on why this is so?
