Is it possible to access header fields in received emails using the CDONTS 
Session object? I'd like to pass some hidden data in a custom header field 
in outgoing email, which isn't a problem. When a recipient reply's, I'd 
like to verify the data in the hidden header field, which I'm no sure how 
to do. The only way I can think of is with FSO, which I'd really rather 
not do.... TIA!
