[PLUG-TALK] A question of ISP behaviors

[wes]

It's not that outbound mail "bypasses" spam filtering, it's that the two
processes are completely different. Totally different sets of rules are
used to judge the worthiness of inbound vs outbound mail.

Spamcop.net has a form where you can copy/paste the spam email (with
headers) and they'll forward it on to the appropriate party for you. You
may be better served using that method. Although, it looks like they make
you sign up with them first nowadays.
