Swift SMTP Mailer WPMU Plugin initial release

Swift SMTP Mailer WPMU Plugin initial release

This plugin uses Swift Mailer library instead of PHPMailer. Why?

Check out the comparison here: http://www.swiftmailer.org/phpmailer/

The unique feature of SwiftMailer is that it also supports TLS, which is used by Gmail. If you are using Google Apps for Domain Email Hosting, this is a must-have.

This WPMU plugin is based on Swift SMTP Plugin made by ShiftThis. This initial release just removed the plugin option pages and made it compatible with WPMU. An improved version with option page is under development.

Download from WPMUdev.org
