Don't worry, it could be worse.
Exchange 2003 and 2007 won't respond with an OoO for every incoming
message. Exchange 2003 won't respond if there is a header like
"Precedence: junk" or "Precedence: bulk", Exchange 2007 respects some
additional headers like "X-Auto-Response-Suppress: OOF". It's all in
their knowledge-base, so kick your Exchange-admin if he doesn't know
about it.
Anyway, if your gateway can detect spam it can mark each message in a
way that prevents Exchnge from sending OoO. Here we use exim to mark
each message with a spam-value which is used to route messages in an
Exchange-Junk-folder and make sure there is a Precedence-Header to avoid
OoO.
Of course you can use other conditions to have exim decide wheter or not
Exchange should send OoO.
