Always make sure you have a reverse ptr record as well as resolving
forward helo lookups for all your SMTP servers. Seen this where you may
have multiple mail servers but not all have mx records.

Hi is there anyway to change this so that it works better?
WARN - Mail server host name in greeting
WARNING: One or more of your mail servers is claiming to be a host other
than what it really is (the SMTP greeting should be a 3-digit code,
followed by a space or a dash, then the host name). If your mail server
sends out E-mail using this domain in its EHLO or HELO, your E-mail
might get blocked by anti-spam software. This is also a technical
violation of RFC821 <http://www.DNSstuff.com/pages/rfc821.htm>  4.3 (and
RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should
have an A record pointing back to the same server. Note that this one
test may use a cached DNS record.
