Anyone know what could cause this (see attached file)? This happened for about 2 hours last night and resolved itself on its own.

Hi jody,

This is caused by some spammer trying to use SMTP AUTH to the Barracuda to attempt to send email outbound. An upcoming firmware should block them after a certain amount of retry failures.
