Look guys, I hate spam as much as the next guy. But I still think the solution you've come up with is unecessarily penalizing legitimate e-mail. Based on perusing AOL's web page, I think that's what happening here is quite simple: You're using the same sendmail ruleset to filter BOTH RCPT TO: addresses *and* MAIL FROM: addresses. To be perfectly blunt, This is laziness in implementation on your part, and you shouldn't be quoting standards to justify it (especially when the standards don't support your claim). Filtering RCPT TO: is just fine (RFC1123 does say "A Sender-SMTP SHOULD NOT send a RCPT TO: command containing an explicit source route using the "@...:" address form." I support your move to *not* relay other people's e-mail for them. Filtering MAIL FROM: is not mentioned anywhere in RFC 1123, AND IS BREAKING EXISTING, LEGITIMATE, E-MAIL. This is my last word on the subject. After all, the only legitimate recourse I have is to recommend that my correspondents switch to other, less draconian, service providers, and I've already done that. -- Harald Koch <[log in to unmask]>
