Mac.com email sillyness

You’d have thought Apple would know how to do email right, but sadly it appears not. A message I sent to the Beowulf list today generated a bounce from a mac.com email address back to me rather than to the envelope sender – very naughty as RFC-2821 says:

If an SMTP server has accepted the task of relaying the mail and later finds that the destination is incorrect or that the mail cannot be delivered for some other reason, then it MUST construct an “undeliverable mail” notification message and send it to the originator of the undeliverable mail (as indicated by the reverse-path).

I wonder if they read their Postmaster email ?
