FYI I'm subscribed to cypherpunks from one address; I post to it from a second; my From: line is a third. I sometimes use a fourth address to post.
You're not the only one who does that.
I'm not sure how you're going to handle that, but you might want to consider semi-automated ways of extracting addresses from "known good" posts, to the extent that any of mine fit that category.
Since the goal is to block spam, not to prevent all non-subscribed posters from posting, I put that in place before I announced the list. Bounces (from not being on the posters list) go to me. If it looks like it's not spam, I have a script which strips off the outer envelope and forwards the mail to the list, adding the contents of the From: line to a list of addresses that's sorted into the major posters list. So far I've added 39 addresses that way, 5 of which appear to be remailers. Of the rest, roughly half are people who're cross-posting from other lists like coderpunks or cryptography (or both), and the rest are people who're posting from alternate addresses. There's 2-3 spam emails for every list email. Previously I'd been filtering most of the spam. I had no idea it'd gotten this bad. -- Eric Murray Consulting Security Architect SecureDesign LLC http://www.securedesignllc.com PGP keyid:E03F65E5
