Wrong again. By default in versions of sendmail since 4.9, all sent mails are logged right along with the failures--and this includes the IP address from which the connection was made to the SMTP server.
Well that's ALMOST right. Sendmail (and most other programs for that matter) allow different levels of logging. Tell sendmail not to log and it won't.
Finding open relays that don't do logging is difficult at best.
Nah, there's all kinds of ways around that. If it was as simple as grabbing the source address in a sendmail log most of the spammers would have been put out of business a long! time ago. As to finding them, those socialist bastards at ORBS and the like keep handy lists available.
very good chance at hitting something
Again, I ask you to produce an example of an open relay that you are reasonably sure does not do logging.
Irrelevant. Forge your source IP headers. ____________________________________________________________________ He is able who thinks he is able. Buddha The Armadillo Group ,::////;::-.
