We ran into the same problem, but it occurs when clueless users or
admins setup autoresponders yet send stuff in. 

RT properly sets autoresponses with Precedence: bulk, but many OOO
responders and such ignore this and autoreply anyway creating a
brand-new message without any of the original message included. Of
course, this creates a new ticket, which generates an autoreply. Sigh.
Would someone please kick Bill G. in the nuts for me??? 

Anyway, I'm working on my own pattern list which I will use in a mail
filter before it even gets to RT. It seems that this would be the
easiest to implement. I'm not sure yet if I will do this via procmail or
an exim filter, but I'm leaning towards exim filters.
