To edit an existing Universal Email instance, open the Server behaviors panel. Window -> Server Behaviors. In the Server Behaviors list, double click the universal Email server behavior.
If you are testing on your local computer, you will need to have an SMTP server installed.
It is better to test Universal Email on the production server using their SMTP server.
success with universal Email is dependent on a few factors:
1) Using the correct email object. Universal Email has support for the PHP Mail object and PEAR mail using SMTP.
The PEAR Mail option will allow you to pass authentication credentials to the SMTP server. you should contact your host to determine which one they will support.
2) Make sure to use the proper SMTP server address.
3) A proper;y formatted form. The form should be set to use the POST method and to POST to itself.
4) Do not use the same address in the To section as is used in the From section.
This will cause the email to be treated as spam.
