No, it was not. There is also a pending bug, numbrer 65, related to this issue. I was hoping to implement this feature and also to test it. However, our SMTP server does not require authentication for sending messages. Zach Cox wrote:

My SMTP server needs a username/password specified even when connecting locally on localhost. I noticed this related thread:

Was SMTP auth ever implemented in logback?

Thanks, Zach
