Doing it with a milter will be fine if Julian says he has no plans,
our MTA handles it all MailScanner only handles the virus scanning
it works pretty well now, just enforcing rfc1912 reduced spam by 80%
the rbl's get about 15% our sendmail mc options catch 4.9%
on avgs, so theres no way in hell im going to drag the servers down by
useing SA, it just aint gunna happen, simple as that.
tried it once, the load went through the roof.
