 [SOLVED] PRT, RDNS, Deferred, And more...
So I keep getting odd errors related to PTR, RDNS, and all that. Now I believe my PTR and RDNS are fixed according to our host and mxtoolbox diagnostics. But I still have errors like this:
[xxx.xxx.xxx.xxx] refused to talk to me: 554-5.7.1 - connection refused. ip name lookup failed for xxx.xxx.xxx.50.
The strange thing is, .50 is my firewall's address, not my mail server address, that is .97. RDNS and PTR all point to .97 as well.
Anyone have any ideas on this? |
