I have setup a Windows 2012R2 Cloud server at Rackspace.<br />
I have installed the latest 64 bit version of Icewarp on the machine.<br />
I have gone to name.com and setup a mail.X.com A reference to the IP address of the server.<br />
I have gone to the icewarp server and added a new account for x@x.com<br />
In the Cloud Server's firewall, I have added a rule for opening these ports:<br />
Mail: smtp, http, pop3, imap 25,80,110,143<br />
I probably don't need http.<br />
<br />
I have gone to my local Outlook and added a new account for x@x.com.<br />
I run the &quot;test&quot;<br />
It errors with:<br />
Outlook cannot connect to your outgoing SMTP e-mail server.<br />
I have tried this test with the Windows Firewall on the cloud server turned off as well.<br />
<br />
What am I missing?<br />
<br />
thanks!

Mail server Setup on Windows 2012 R2: cannot connect to your outgoing SMTP e-mail server

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.
