I am having some spam issues with my mail server.

I have multiple servers that are relaying mail through my mail server. I am wanting to know if PTR records for these servers will have any effect with regards to recipient mail servers marking mail as spam?

I don't think I follow. In this case, aren't you the recipient mail server? –  David Schwartz Nov 8 '12 at 1:23

Naw... The PTR records for the other servers shouldn't matter. You'll pretty much only need reverse PTR records on the relay server.

Please make sure you limit who can relay through that server. You want to avoid having an open relay.

If those other servers are sending spam or have been compromised, what they send can affect the reputation of your relay server. That can affect your spam ranking.
