All correctly implemented SMTP mailers _MUST_ modify the envelope sender address when forwarding a message to the target address(es) of an alias.
That's a new requirement in a new RFC. How many sites are there in the world that run older MTAs that do not necessarily always implement this rule? Indeed, are there any MTAs which exist today that enforce this rule in all cases? Even if you do have an MTA which implements this rule, what if all you have is the alias, and there is no "-owner" or "owner-" address defined?
So, you run a big site, with tens of millions of customers. Are you going to tell them all to "piss off" if they're subscribed to a mailing list that is not implemented according to this rule?
