Once a message has arrived at a mailbox (your POP3 service), you have
lost the envelope details, and you should not try to resubmit that
message to an MTA .. with CC from a mailing list being one of the
canonical examples of what will go wrong.
Instead of looking to Exim to fix the problem, I would recommend asking
fetchmail itself to do local delivery, possibly via procmail. Keep your
exim for outgoing messages only.
I expect that there are ways around the problem, but you will end up
with an unusual and difficult Exim config, rather than a set of simple
configs using the tools the way they are intended.
