In order to deliver mail to a user AND to an alias of that user,
specify that user in the expansion of that user's alias, thusly:

        flump: flump, other...

That works with Postfix AND with Sendmail.

The \user form is no longer supported by Postfix. Fixing that
requires butchering of the tok822_parse module, which is code
that I prefer to leave alone.
