We use a shared GW resource to receive support emails. We also use the resource to broadcast messages to all of our users; however, when user has a vacation rule set up, I'd prefer to have a rule that automatically trashes those auto-reply emails instead of clogging up the inbox. I currently have a rule set up to try to catch auto-reply vacation rules from users, but it's not perfect and occasionally one slips through and is trashed by my rule.

Is there any way to create such a rule? It would be nice if GW had a way to recognize an rule based reply over a user typed reply. That would make it much easier.
