What do I need to do to correct this error?

WARNING: One or more of your mailservers 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 mailserver 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 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.


mail.hchd.us claims to be invalid hostname '**********************************************************************************************': <br />   220 ********************************************************************************************** <br />

When I telnet to mail.hchd.us, the system only responds with "command not recognized".  That may be part of the problem - it's difficult to say.

What product are you using for e-mail?
