I do find it useful in general to have the envelope recipient
appearing in the Received: header, but Sendmail V8 will only do this
if there is a single recipient. So make it two recipients instead.
e.g. from my alias file:
# This address is the bit-bucket. It is useful below for mailing lists.
# If you send to a list expansion alias *and* this, then sendmail will
# not write the envelope recipient into the trace headers, as there
# is more than one envelope recipient.
devnull: /dev/null
...
testing: "|/disk/mail/majordomo/bin/wrapper resend -l testing -h haymarket.ed.ac.uk testing-outgoing devnull"
You'll get extra entries in the sendmail log for messages being
delivered to devnull, but you won't get the recipient name appearing
in the Received: header.
