Mail server host name in greeting

I am having the following report when doing a dnsreport.

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.

mail.darjeelingteashop.com claims to be non-existent host linux1.snonline.com:
220 linux1.snonline.com ESMTP

My main box hostname is linux1.snonline.com and darjeelingteashop.com is an account on this box.

How do I sove this problem.
