I would recommend setting up procmail on your incoming account to automatically detect these incoming messages (based on subject line and/or From: address, for example), and then send back a canned response describing the situation. You could indicate in the message that they should check their headers of the email, and see that the From: address was forged/bogus, and point out what sites were -really- involved in sending the message. Do it simply, and apologetically, with no attitude, and that will satisfy most users. Then after sending the canned response, procmail would just drop the message, and you'd never see it. [If you don't know how to use procmail, learn. It is definitely a tool worth its weight in gold.] If you were to just block email from aol.com, or just drop it with no action at all, it would most likely irritate users trying to contact you even further, and likely get you a reputation for not caring about junk email. > A spammer recently sent an email to members@aol.com using a bogus from > address as a user in our domain.
