| 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. glmfav01.fciconnect.com claims to be invalid hostname 'Ready': 220 Ready glmfav02.fciconnect.com claims to be invalid hostname 'Ready': 220 Ready glmfav03.fciconnect.com claims to be invalid hostname 'Ready': 220 Ready |

1. 你的helo dns名的dns名要在dns有相应的A记录, 且要和真实的IP相匹配.
