Point of clarification: As i understand it, the ptr record can return the host for an ip. If it returns the wrong host then folks who do reverse lookups will reject your email. If this is correct, can you have virtual ipless mail hosts from a practical standpoint? (won't they all yield a mismatch on the reverse lookup?). Or do you add cname records for each. Or do you just add ptr records for each? Both? None? Also, my upstream dsl provider has my ip addresses listed to them in a reverse lookup. They sort of know that this is a problem, cause when i asked about the hemmed and hawed and said yes, we did this temportarily, bla bla bla. So another question, is, is it enough to have them add a ptr record to refer to my name servers to get the mail to work correctly, or must they add every virtual mail host (seems unreasonable) Any help appreciated.
