This has been asked before on the list, but never really answered....
because it can't be(!)...
OoO/vacation really is a phenomenon, not a standardised thing, so you
don't have much to go by... Other than scoring the actual text
(usually in the subject), I don't think you have many options. If you
use Postfix, you could make a DISCARDing header_check, but then....
that might end badly:-).

The sane solution is to not allow OoO, and encourage your user to use
other measures (like "mailbox delegations" etc). Unfortunately PHBs
are rarely sane...:-)
