I receive several logs per day via email, either from testing operations, server status or backup resumes.

Can I some how disable the notification balloon either by a specific email address, the email subject or any other possible filter, as to not be constantly notified about the success operations?

I've looked within the Notify OSD Configuration, but couldn't find any option to this end.

Since the email comes with different information when errors occur, I already have filters within Thunderbird as to move error logs to a folder that I keep tabs on...

^{If relevant, I'm using Ubuntu 12.04 fully updated, and Thunderbird 15.0.1.}
