Comparing a email message to a preceding email message

[Darren Reely]

What are you up to?  :)

I'm no e-mail expert, but off the top of my head...  

I'd place all the Message-ID: header contents from powerh-list B into
another file.  Presumably indexed.  Then when comparing a message from the
first list, I'd simply read from the index.  You can figure out the rest
from this idea.
