Unfortunately, I know of none.  There is no standard for OOO, 
therefore there is no definition of, say, a particular header that 
LISTSERV could provide that would prevent the recipient MTA from 
sending the OOO back, or again say, some header provided by the 
recipient MTA for all OOO that you could key on to filter it out.

If everybody could agree on a standard way to identify mail as OOO, 
we'd be a lot closer to a solution.  If you look back through the 
archives of this list and of LSTOWN-L I'm pretty sure you'll see this 
same complaint going back quite a number of years.  Everybody talks 
about the problem but the people who actually have control over OOO 
(ie, the MTA vendors whose MTAs generate the OOO in the first place) 
do nothing to help solve it.
