Rather than resending a copy of the message to each and every recipient, how
about just replacing the To: and Cc: headers with something innocuous,
effectively making all of the recipients blind-carbon-copy (Bcc:) recipients
instead?

Another approach might be to send to groups of recipients: 1) insiders, who
get full headers, and 2) outsiders, who get whitewashed headers.

Either way, the mail server itself would only have to deliver a couple of
messages (to many recipients) rather than hundreds of messages to individual
recipients with the attendant load-multiplying effect.
