Hmm, the onses who block everything and cut wires off send 0 spam.

Do all of Comcast's markets block port 25? Is there a correlation between spam volume and the ones that do (or don't)?
In any event the malware is already ahead of port 25 blocking and is leveraging ISP smarthosting. SMTP-Auth is the pill to ease this pain/

For example, about 2 months ago, comcast decided to block outgoing port 25 from my entire neighborhood. I called comcast, and while sitting on hold I had the idea to setup a ssh tunnel to a machine at work and viola problem solved before anyone from comcast even answered the phone.
