Um, I couldn't stand this policy while waiting for Sarge.

But yes, if dovecot's LDA would honour something like .forward
files, I'd be happy.

Actually, the forward files functionality is mail forwarding per user, this is you setup two (independed) maildrops per recipient; it's a feature of the MTA, not of the MDA.

One maildrop is the mailbox of the local user, the other one is the auto-responder.

Maybe, you could also name it "aliasing", you alias the local recipient to the local recipient himself and the responder (double the mail, like if you would forward the mail to two different remote addresses). In sendmail the main difference between ".forward" and aliases is that aliases are executed with the permission of the MTA, but .forwards with the permissions of the user. I don't know postfix, so I cannot use the correct terms of it.

Sendmail uses different mailers (exim calls them transports, if I remember correctly) for the two different maildrops, "scripts" are invoked by the virtual "*prog*" mailer, whereas the spooling into a local mailbox is performed by the "local" mailer, which is bound to e.g. Dovecot deliver.

http://www.postfix.org/local.8.html
"An alias or ~/.forward file may list  any  combination  of
       external   commands,  destination  file  names,  :include:
       directives, or mail addresses.  See aliases(5) for a  pre-
       cise  description. Each line in a user's .forward file has
       the same syntax as the right-hand part of an alias."
this paragraphe should cover what I mean (section: SYSTEM-WIDE AND USER-LEVEL ALIASING).
