Not using spam filtering ... I don't like the chances of false positives or negatives. My idea is similar to the idea of abandoning a phone number if you get too many prank calls. Similar to abandoning a phone number, when I abandon an email address, I don't even see the spam traffic - I'm not filtering it out. I've got a bit of a description of what I'm doing at the following URL. http://forums.whirlpool.net.au/forum-replies.cfm?t=184280#r4 It's not going to be perfect, nor am I claiming it to be, however, I've found it to be pretty effective.

I can't see the logical progression from being able to run an MTA, to getting Internet connectivity for free. Of course, if you're really making that offer, I'm quite interested :-) Why do I run an MTA, and want that ability ? Because I run my own domain name (nosense.org), allowing my email addresses to be ISP independent, and I use multiple subdomains for email, which means I fairly regularly need to change the MTA configuration. My broadly, I don't want to have to rely on an ISP running an MTA configuration which may not best suit my needs, when those needs are or may be different from the general requirements of their user base. It's sort of a "if you want something done properly, do it yourself" situation.
