I don't know if it's public knowledge yet or not, but beginning around the
20th, ACS has been doing spam filtering. They don't delete anything, but
they are evaluating it and adding a header to the email. A copy of the
header is below:
X-ACS-Spam-Status: no
X-Scanned-By: MIMEDefang 2.30 (www . roaringpenguin . com / mimedefang)
There are additional X- headers added also, but those were the interesting
ones.
It seems to run on top of SpamAssassin & Sendmail, but I'm not yet sure what
it adds that they don't already provide.
This morning I checked my home email, and 9 out of 10 spams were set to
"X-ACS-Spam-Status: yes". Not too bad. I set my home email (Mozilla) to
delete any that were flagged as spam. So far no false positives, but I'm
watching for them. The mail filter on Mozilla moves them to Trash, so it's
easy to check. About any modern email client should let you do the same
thing.
If you're using ACS as your provider or have clients/friends that are, you
might want to check into that. There's no charge - they just do it as it
comes in. Funny that they haven't announced it though, which leads me to
think it may be experimental to some degree. They probably want to hammer
on it for a while before they let the world know, to tune the filters and
minimize false positives. Since they don't do anything w/the mail other
than add a header, there's no danger of legitimate mail being dropped.
Pretty nifty...
