Dear List,
I was curious how organizations typically score mail which comes from
their own domain(s). Obviously spammers will spoof the source domain in
hopes that you have whitelisted your domain or give "special treatment"
from mail originating from within your own org.
Mail may come in from a blackberry or something which is external from
the org and still have your domain name on it--and is legit. Would it
make sense to add a couple of negative points from mails coming from
your own domain to reduce false tagging?
No it would not, for exactly the reason you specified.
I've never seen mail from a crackberry get tagged, but if you're
concerned about that, you can whitelist specific addresses (or all of
provider.blackberry.net if you trust them to block spam).
Notice the Return-Path in most providers crackberry mail contains
[EMAIL PROTECTED]
Example:
Return-Path: <[EMAIL PROTECTED]>
Received: from smtp02.bwc.na.blackberry.net
(smtp02.bwc.na.blackberry.net [206.51.26.185])
by your.mx (8.13.1/8.13.1) with ESMTP id j6FC5Nao032001
for <[EMAIL PROTECTED]>; Fri, 15 Jul 2005 08:05:24 -0400
