WARN Mail server host name in greeting 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.
