The main thing to do is to flag mismatches (I believe
Outlook supports a number of X-Headers that can be used for such?)
to let your users know that something may be wrong.
Outlook does let you write a rule to look for an arbitrary text string in
the headers. It doesn't support regexp's, but it at least looks for the
string as a substring. That can include the header name, as well, and the
name doesn't have to be an X-header type. Therefore, if your mailer flags
inconsistent return-path and From: addresses by writing a header that
includes a consistent text string, you can easily write a rule to flag that
message by, for instance, displaying it in a different color in the inbox.
Outlook Express, unfortunately, only has the capability to search a few
specific headers, which makes it useless for a lot of preprocessors. It
could not perform your desired function unless you modified the subject line
(ugh) or added a special bogus address to the cc: or another common header
(double ugh). It's too bad that so many people use this rather incapable
MUA.
