After we installed our mamboserver (you are browsing it right now), we realized that sending registration emails to newly created accounts does not work. Of course it did not work because we were not running SMTP server on localhost.

If you know external SMTP server which does not require authentication, you only need to modify SMTP configuration php.ini file in your Apache directory.

We have been looking for solution how to use external SMTP server which requires authentication for registration and other email features in mambo because PHP's mail() function does not support authentication.
