Basically you add a rediect router after the router than handles local
users, in that router you check the domain name but not the local part
and then redirect all mail to wherever you want it.

That's going to treat all mail for your domain as valid

This comes up pretty bogus for human users, if they make a typo they
get no feedback. :(

Ideally you want to do a control=fakereject in the data acl so the
sender gets some feedback, but that can be hard to do if there are
multiple rcpts - so setting that up is fairly complex,

The first step is to add 'verify=no' to the router added above,
and then it gets complicated...
