The fact that they're rejecting on a 5xx error based on no DNS PTR is a
bit harsh.  While I'm all for requiring all hosts to have valid PTR
records, there are times when transient or problem servers can cause a
DNS lookup failure or miss, etc.  If anything they should be returning a
4xx to have the remote host"try again later".
