I setup monit just recently, but I can't get the email notification to work. I get the following error:

"Sendmail error: 550-(#*$!xx.#*$!xx.com) [xx.#*$!.#*$!.xx] is currently not permitted to relay"

I guess it's because my SMTP server requires user authentication, but I can't figure out how to setup monit to authenticate to the SMTP server.

Any help would be appreciated!
