No, sorry. But you could use MCP (Message Content Protection) to catch
messages which match the subject you are looking for.

One of the reasons I haven't implemented it is the purely practical matter
of defining how you could express a rule containing any arbitrary text (eg.
spaces, quotes, slashes etc), while still ending up with a rule that can
actually be parsed. If you, say, were writing a rule for "Spam Actions"
(which takes several keywords as its result), you could end up with this:
Subject:    this is random text to match   deliver forward
How on earth do I parse that? Where does the subject end and the result
(deliver forward) start?

If you can come up with a decent solution to this problem, I'll have a
crack at writing it.
