Creating a Secure SMTP Submission Service

Postby Elric Pedder » Mon Feb 13th, 2012 9:03pm

This tutorial will show you how to create a secure SMTP service where your users can post e-mail messages from mail clients and mobile devices. The service will be encrypted with SSL and mail sent in this manner cannot be seen by anybody able to capture the data as it travels over the Internet. In order to configure a secure service in Mailtraq you must first have an SSL certificate. See Creating a Self-Signed SSL Certificate to create your own certificate.

To begin, right-click on the Services node in the Mailtraq Console tree and select New -> Simple Mail Transport Protocol (SMTP).


When the dialogue appears, change the TCP/IP port from 25 to 465 which is the standard port for secure SMTP.


Click on the Relay tab and check Use SMTP User Authentication which prevents unauthorised users from submitting mail.


Click on the SSL tab and select Implicit Mode. Make sure you have selected a certificate from the drop-down box below.


Now click OK and start the new service.
