You probably have wrong DNS PTR. Check your domain at http://www.mxtoolbox.com/

Yes way.

This is not inside your server. The receiving mail server is rejecting your mail because there is no host name associated with your public IP address (80.80.236.167). Ask your ISP (Safehost?) to set up a PTR record for 80.80.236.167 in their DNS. It's the only way.

And for the record; there is no PTR record defined for 80.80.236.167. I checked.

Boing:~ torw$ host 80.80.236.167
Host 167.236.80.80.in-addr.arpa. not found: 3(NXDOMAIN)
Boing:~ torw$
