You can configure it manually by creating a 'virtual' file and pointing
postfix to it, e.g. by adding hash:/etc/postfix/virtual to
virtual_alias_maps, and putting a line like this into it: catchall at

and running `postmap /etc/postfix/virtual` on it.

That should turn catchall at into a catchall address for The catchall address doesn't have to be in the domain, of
course; and I do believe the full address is looked up first, so it will
not take precedence.

Presumably, the static file could be replaced with some sort of
automatic lookup based on one of postfix's normal mechanisms for this,
but haven't tried it...
