To my knowledge, the ONE thing that gmail checks is the Message-ID:
header, if that matches, it is a duplicate and dropped. It is not
checking for the messages being "identical", it is detecting
"duplicates", as defined by the RFCs for Email (if two messages are
different, they must have different Message-ID:s).
