[Dbmail] Forwarded Mail Identification

[Nataraj S Narayan]

Hi

Is there a way to identify a Forwarded message from any E-mail client, 
in the DBmail database?

Is there any flag field associated with mail forwarding ?

I need to rewrite the 'Sender' to the orginal Sender, for those mails 
forwarded in the local domain.
