The problem there is that some of the users retrieve their email via POP. > Mail clients, normally remove smtp headers when forwarding messages.

None of the programs they use seem to support such a feature. Sounds very similar to a forward, just leaves headers intact?

I've only seen one so far, and it was vaugely spam.. an email from my credit card company after signing up for online account management.
