Thanks, David! The mimedefang package in lenny doesn't create a
mimedefang-ip-key file by default or distributes the gen-ip-validator.pl
script. I created a key by hand with the gen-ip-validator.pl script from
the tarball. Running mimedefang with the mimedefang-ip-key solved my
problem without changing anything in mimedefang-milter and now I can
detect locally-submitted and resent mails (stream_by_domain) by checking
$RelayAddr for "127.0.0.1".

Ciao,
