Vacation notices can take any form. There's no standard protocol for them.
As a result, blocking only vacation messages is a difficult if not
impossible task to do reliably. On the lists I manage, I simply set those
subscriptions to NOMAIL whenever I get a vacation message. I also send out
an ocassional reminder that people should avoid using vacation messages
unless they sign off the list first or set their subscription options to
NOMAIL first.
