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.
