Hi All,<br />
<br />
I have had a clients email server reject mail sent from one of my domains.<br />
<br />
Their IT guy provided this info.<br />
<br />
SMTP Reverse DNS Mismatch &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Warning - Reverse DNS does not match SMTP Banner<br />
<br />
We own a vps on which the sending mail comes from.<br />
<br />
what do I need to do?<br />
<br />
Some forums suggest that we do not have a reverse DNS entry setup?<br />
<br />
Any info would be great.

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
