Looking at the error msg briefly I think the problem is with the DNS records:
> rejected: cannot find your hostname, [205.234.223.198] (in reply to RCPT
> TO command) (in reply to RCPT TO command))
$ host 205.234.223.198
198.223.234.205.in-addr.arpa domain name pointer mx4.servershost.net.
$ host mx4.servershost.net
mx4.servershost.net has address 66.225.237.241
As you can see the DNS resolves to different IP address than given by
the PTR record. Some email systems consider this as an indication of a
misconfigured mail server (spam sending attempt) and refuse to relay.
Best,
Peter
