Thus spake Steve Snyder (swsnyder@snydernet.net):
Got another threatening e-mail from my ISP today, prompted by another SpamCop complaint regarding spam run through HotMail. HotMail records the address of the originating server and that, again, is my exit node.
So I have to curtail exit access to HotMail. Yeah, it sucks, but I know of no way to block the sending of webmail while still allowing it to be retrieved.
Make sure this is done via exit policy and not iptables or DNS filter.
Also, are you sure you have the whole hotmail netblock?
And make sure that you similarly block all webmail remailers. Hotmail aren't the only ones to stick "X-Originating-IP" headers in the mail.
But seriously, I think this is a bad idea. Much better to explain to your ISP what has happened and why you are not responsible. I have done exactly that with my ISP when they shovelled spamcop crud my way. They understood entirely, reacted like professionals and told spamcop where to go. If your provider won't help, it may be time to switch providers.

The text file for RFC 854 contains exactly 854 lines. Do you think there is any cosmic significance in this?
