This is not a BIND question but I hope people here will know the answer. We are switching service providers and I understand that many email SPAM prevention systems insist on the reverse DNS matching the forward DNS. If I have two A records for our mail server and the reverse record matches one of them, will that be good enough. Or will the fact that the other A record does not match cause trouble
when you have two A-recods then you have two IP's each of them should have a PTR with *only* the name of the A-record and in a good setup "smtp_helo_name" matchs too
