    Exim with exiscan-acl compiled in (exim-daemon-heavy in Debian has it, not
sure if that strain made it into Ubuntu).  I also use SA-Exim for the SA
filtering since it is a bit more rubust at that portion than exiscan-acl.
But, yes, that is how my mail server works right now.  It does basic checks
pre-data and a content filter post-data but pre-acceptance.

    Yes.  550 is legal after the data block.  In fact in my many discussions
on virus/spam filtering it's the consensus among people I trust and are a tad
more versed with the RFCs than I am that this is the proper thing to do since
it places the bounce where it should be and avoids the Hotmail/Yahoo/GMail of
accept and silently drop.

    Well, that is silly.  I presume this was from one of my mutt messages?
I'm running mutt on the same machine as the SMTP server.  It received it from
localhost.  I can put something bogus in there but having a perfectly valid
location, IE "the same damn machine", is frowned upon.  Meh.  I'll have to
check the headers myself (shows how rarely use mutt as a fallback) but thanks
for the heads up.  ;)
