My Role:
Allows admins to manage multiple SMTP servers. A server is randomly chosen for each page request, so that all mail going out of the system is spread across the servers. The GET variable use_smtp_id can be set with the server ID to use for the request.
This module sits on top of the SMTP Authentication Support module to add the ability to manage multiple servers. All mail handling is still done by the SMTP module, which makes use of PHPMailer. PHPMailer supports using SSL or TLS encryption as long as the OpenSSL functions are available in your installation of PHP. More information about PHPMailer can be found here: http://phpmailer.worxware.com/.
