We used to do something like that on cus.cam.ac.uk, but the list was
always getting out of date. We now have
condition = ${if match{$home}{^/(home|group)/}{yes}{no}}
on the userforward and localuser routers (and use verify=recipient
in the RCPT ACL, of course). The effect is to implement a rule that
a userid that has a home directory in a weird place, and _isn't_ in
the system aliases file, is an invalid local part.
