You'll have to add a header in filter_end with the list of recipients,
but only for the archive mail.  I'm sure this is possible, but I'm not
sure how it would be done.

BCC isn't done via mail headers;  it's done by the sending MUA issuing
extra SMTP RCTP TO commands for addresses that it leaves out of the "To"
line.  (For CC, it includes addresses in a CC: header.)

MIMEDefang should have the list of recipients in @Recipients at one
stage or another.
