Outlook has rules to look at only some of the headers (the ones the sender
inserted into their message that is sent under the DATA command to their
SMTP server). The spammer cannot alter the headers that get prepended by
the SMTP server but they can try to fool you by inserting bogus Received
header. Other than From, Subject, and basic sender-editable headers,
Outlook cannot be told which specific headers to interrogate. It has a rule
to check for message headers to contain some string but that doesn't specify
which header has that string. You could enter "Received: ..." to try to
have it interrogate the Received headers but unless the target string
immediately following the header, as in "Received: ir2.motleyfool.com" so
you could test on ir2.motleyfool.com being in the Received header, you can't
find a string anywhere else in the header. And you don't get to specify
which Received header to look in. Outlook's rule are very limited in what
they will let you do, and none of them permit the use of regular expressions
within a string.

Replying to wanted e-mail (presuming you have a means of determining such
which you haven't specifically disclosed) with an auto-reply would be okay.
Replying to "unwanted" e-mail (which you define) would NOT be wise if, for
example, you were talking about spam. A pheasant hiding in the corn field
stands a much better chance of not getting shot then one that gets flushed
out and flies out into the open above the corn. Just hide by deleting the
crap. Once you announce yourself to a spammer, you put yourself on their
plate for them to poke at more often (because they now know the account is
not only defined but is also monitored). Of course, if your intent it to
actually get shot at more often (i.e., you're deliberately trying to run a
spam trap), then go ahead and announce to the spammers that your e-mail
account is actively monitored and they actually reached a valid account.

See the following article on how to make Outlook emulate an auto-respond
server (but obviously Outlook has to be running to perform the action):

OL2002: How to Emulate the Out of Office Assistant
http://support.microsoft.com/?kbid=311107

Since part of this solution involves a rule, you could combine whatever rule
you are now using to detect "unwanted" messages and incorporate it into this
rule so it replies when the same condition(s) occur.
