what do you intend to do when the message has >1 recipient
within AOL (such that it might be delivered with several
RCPT TO statements in a single transaction)? If you put
all the addressees in the headers in plaintext, this could
reveal Bcc: information which would not usually be
available to the recipients -- it would be better to
encrypt the data with some secret known only to you if you
do put it in the header. Alternatively you could ensure
that each delivery is made in a separate SMTP transaction
(e.g. with max_rcpt = 1 in the transport), in which case
the simpler approach would work. Either way, you could add
the header with a warn statement in an ACL or headers_add
in a router or transport.
