Unfortunately it is not clear from your description how the mail is being 
handled.  When you say "This java application POP's it's email", is it 
always POPing from a single mailbox, or could it POP from various 
mailboxes?  Anyway, if you just want to add a header when you know the 
envelope recipient, just pipe the message through this filter:

	formail -A "X-envelope-to: $recipient"

If the recipient is not defined then that is another story . . .
