PTR, reverse DNS records for dedicated server

[andychev]

I had a similar problem a while back but due a change in circumstances I never needed it to be resolved. It happens with hotmail and aol address's. They cant do a reverse dns on the ip so reject the message. Try your ip here to confirm this is the problem:

There is no error message. The emails go out but don't get to the destination or bounce.
