I have been unfairly hit by anti-spam measures several times, so I fully agree with the EFF statement [1]: Anti-spam measures must not punish innocent senders. My personal experiences: MAPS DUL has a list of dial-up IP addresses, and many (about 10 or 20%?) smtp servers reject mail coming in directly from these addresses, claiming it were spam. See my Anti-DUL [2] page why that is a bad idea (TM). From-based filtering does not work. From a naive POV, it might be a safe bet to consider anything from an email address which has previously been used as From address in a spamming as spam. However, From addresses can trivially be forged, and spammers routinely do that to not get the thousands of delivery failure messages. Often, they use invalid or throw-away addresses, which will only clog your database, but the premier assholes use addresses in their recipients database as From. A spammer once did this to me, sending out pheromone advertizing with ben.bucksch/at/beonex.com as From address. Imagine the fun on my part. Now, if that meant that my address would from now on be blocked my some people, that would be a real problem. Even worse would it be, if my mail were not blocked, but silently (for me as sender) be deleted. So, IMO, the best thing to do would be to bounce the mail. I oppose anything in Mailnews that encourages users to (probably unknowingly) reject (or even silently delete) mail which *could* be real individual mail from a real person. If you do it carefully and responsibly, this could be a quite popular feature. Ben [1] <http://www.eff.org/effector/HTML/effect14.31.html#II> [2] <http://www.bucksch.com/1/opinion/dul/>
