how to know programmatically if a mail is received or sent

[Database Administrator]

I have to develop an agent running on all documents in a folder; the
agent will do some things if the document is a received mail, other
things if the document is sent.

I can't use the name of the user to distinguish them because several
mail file has chenged several owners in times.

I know that incoming internet mail has then field "recieved", that is
not present in outgone mail. But the same field is not present in
incoming mail from the same Domino Domain; so, just using that field, I
can't distinguish internal mail sent mail from received ones.

Any ideas will be appreciated
