Not yet. It's on the todo list but we haven't had time to search for a good way to talk to an SMTP server directly from the PHP code.

Any recommendation.

On a related note: in v5 we log outgoing messages and handle Return-Path notifications, which means we handle delivery errors almost automatically.

phpMailer is very popular
http://sourceforge.net/projects/phpmailer/

i see.That'd be more secure and easier to track/investigate.Looking forward to it.
