We are no longer receiving email notifications, generated from my custom rules.  The out of the box email notifications are still getting through.  I have not made any changes to my cusom rules, but they are getting caught in our Barracuda.  They are showing up "Allowed", but remain "Queued".  The only change that occured before this started was my company did maintenance to their firewalls.  Not sure if that might have anything to do with it.  Any ideas?

Thanks
