Way to tell if a message has been processed?

Hi,

I'm trying to find a particular message as a test of effectiveness, but
can't come up with a set of words to find this message (which I do still
have on my IMAP server).  Is there anyway to check a message has in fact
been processed?

Thanks,
Kevin
