SmarterMail SMTP Authentication Bypass for ColdFusion VPSs

To use cfmail and Default SMTP from ColdFusion VPS servers with SmarterMail, 'SMTP Authentication Bypass' needs to be enabled. To use SMTP Authentication Bypass, for cfmail - without authentication, go to Security>>SMTP Authentication Bypass and enter the server's IP address and the localhost IP address of 127.0.0.1.

NOTE: For security reasons it is the best practice to use SMTP Authentication for all cfmail, either with SmarterMail on the VPS or an External SMTP Server, this it to prevent unauthorized emails being sent from the VPS (See the below settings). By default, New ColdFusion 10 Servers with SmarterMail has this disabled.

Using CFMAIL with External SMTP

This second method will allow you to send through an external SMTP server such as mail.example.com. It requires specifying the server, port, useSSL, username, and password attributes as shown below:

<cfmail
  server="mail.example.com"
  port="25"
  useSSL="false"
  username="example@example.com"
  password="mySecretPassword!"
  from="#from#"
  to="#to#"
  subject="Sample CF e-mail">

This is the body of a test email.

</cfmail>
