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 -request instead of . 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. kyle jones ...!uunet!talos!kjones
