When a reverse DNS lookup happens, it all matches. AOL checks this as well as do I. Too many servers out there are set to relay. Setup your servers to only be relayed by those people that are in the database. All others would bounce. This is also the test that AOL will be using when they do an IP followup. Looking at the info at AOL, when they do find an open relay, they send a letter to [EMAIL PROTECTED] and [EMAIL PROTECTED] informing you that you have an open relay. I put one of my own in their system. I would like to know for sure and AOL can assist (even though they are doing it for other reasons) in identifying a problem. When a reverse DNS lookup happens, it compares the dns with the IP number. If they are not matched, the mail bounces. Those on Dynamic IPs will bounce on ANY decent server. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
