Every day I read an email from my server listing every sender's email address where my server has refused to accept the mail and which were sent to one of the three real names my server deals with. It's not a big task, as the overwhelmingly vast majority of refused spam is sent to obviously made-up names on my domains in the hope of getting a bounce to the spoofed From: address. Fifteen or so years ago, out of curiosity, I said to hell with fake email addresses, I'd go on using the Net with a real address (the one in the headers has been my main address all those years) and see if I could deal with the consequences. I've had to give up one of my main weapons, the DNS check, as so many small businesses now outsource to some other small business which doesn't really understand email. Also, a lot of domestic ISPs now give their users PTR records. I've compromised by routing the PTR-less stuff straight to a spam folder. and glancing at it occasionally. It has worked out pretty well, I don't see a lot of spam, because I refuse all the NDR stuff, and don't have a backup mail server. Much of what I do see is 'real' spam, bloody idiots in my own country who genuinely believe that the way to sell me stuff is to send me unsolicited email. Repeatedly. I keep my own blacklist, and the mailing companies and tiny ISPs who provide services to these spammers go into it. I used to complain a lot to abuse addresses, but it never helped, and the big people don't even have abuse addresses now. -- Joe
