[Mailman-Users] Filter vacation messages?

[Michael Schaarwaechter]

Hi,

my problem: I can't recognize a vacation message going to a mailman list
just by taking a look at the header. The Mime type filtering doesn't
help, too. I just need a possibility to filter by the content of the
message. I want to hold back messages saying "am not in the office" and
so on.

Has anybody done this already and can give me a hint?

TIA and cheers,
Michael
