OK, for the archives:

I went with Option 2.  In my sendmail.mc, I added:

LOCAL_CONFIG
H?${u}?X-Original-To: $u

This adds the header X-Original-To with the envelope recipient as the value.

Seems like a hack, but what can you do?  It works.

BTW: No one asked, but I thought I'd just mention that the reason I want to use the envelope recipient address is many bulk-mailing lists will use blind addressing, so you can't use the To: or Cc: headers effectively.

Anyway, sorry for the noise everyone.
