Need to search for an IP address. Can I search all the headers to see
if the IP address is one of the mail servers or originating IP
addresses etc?
If so, How?
Define a rule that used the "with <specific words> in message header"
clause to look for a particular string, like your IP address. Your rule
could move the matched messages to another folder, delete them,
categorize them (so you could edit the view to color code messages in
that category), or whatever action you want (which you didn't identify).
However, you cannot specify regular expressions that will look for the
string to be a particular header or in a particular position within a
header. That is, you cannot specify to look for the IP address only
within the Received headers but only after the "from" host, or only in
the Return-Path header, etc. In Outlook's rule, you can only search if
the string is used *somewhere* in the headers section of the message.
Microsoft has yet to embrace regular expressions.
