This works only if everyone runs a mailer that supports this header.
There is no mention of Errors-To: in RFC822.  Sendmail claims to
support this header, but smail (2.5) certainly does not.  I say
'claims' because I recently had a mailing list that I run flooded with
returned mail from a host running sendmail.  An Errors-To: line was
present in the message in question.

For my money, the right way to avoid bounced mail hitting an entire
mailing list is to make the From: header say <list-name>-request
instead of <list-name>.  This means that recipients must edit the To:
line if they want to reply to the list, but that's a small price to pay.
