Sending separate Bcc and non-bcc copies would be preferable
functionally, but of course requires additional bandwidth. The
bandwidth issue could theoretically be handled by offloading the
"splitting" functionality on an MTA closer to the Internet backbone,
e.g. using an ESMTP extension as Jacob has suggested.
Given my druthers, I'd much rather see it be an extension only to the
MSA SUBMIT protocol and not one that is expected to be implemented in MTAs.
