Identifying Email Messages by IDs

I was wondering if anyone knew whether there is a unique identifier attached to an email that I can use to verify whether emails are the same? I know about the EntryID and PR_SEARCH_KEY, but i need something abit more specific if it exists.

Supposed I forward an email to 3 people. I want to make sure that at most 1 copy of those forwarded emails is added to a database. Is there an identifier that will be shared between those three emails that i can record and use to disallow entry of the other two? Or will I have to add a manual tag somewhere on the email?

thanks

The obvious answer is the Message-ID, which all good emailers use. However, not everyone in the world uses it.
