Great plugin for any type of mail server. The only thing that would be worth to improve is the logging feature. It debug logs has raw data and is great for debugging, but it would be useful if the log would be in a list including the sender, receiver, subject, date/time stamp and a sent/failed status indication.

Even if you do not use an smtp server, it improves the standard mail sending with phpmail
