To start, I just want all bounces to go to a different address.
Then I am puzzled by why you want to mess with Errors-To, which is
``non-standard; discouraged'' according to RFC2076. What's wrong
with sending your mail with an envelope sender of
errors@rocnet.com? (I don't think ns_sendmail
lets you set the envelope sender explicitly, but this is easy enough
to fix.)
