That sounds as if you have only ONE account with the ISP among the 'company'
adressees that the ISP recognizes as a subscriber.

If so, it would be normal that only that addressee appear in 'envelope to'.

Ergo, anything short of subscribing the rest of the accounts to the ISP will
remain a bit of a kludge.

I'm not sure why you don't just have Exim handle all the mail and be done with
it, as it can do a better job with less effort .. but never mind ..

Sounds as if you need TWO Exim instances. One takes the 'raw' input from
getmail, expands the To: and CC:, fowards to the second instance.

The second instance, set to 'require verify = recipient' rejects those that do
not belong to your firm.

No stripping or re-writing needed.

But you would also need errors_to = /dev/null (or yourself) on (at least) the
'up front' Exim if not both, so as to prevent backscatter non-delivery bounces
for the 'To: and 'CC: that were never intended to be yours.

For receiving, it should be simpler to change a DNS entry, cut out the ISP, and
JFDI with one Exim, even if relaying to Exchange.

*Sending* (presuming you have no PTR RR) is where you need the ISP's help.

YMMV
