Why do you specifically want to base it on the filename pattern rather
than on the alias name? To do it by the alias name is already possible
via a lookup, or a complicated expansion string like

  user = "${if eq{$local_part}{abcd}{1234}{\
          ${if eq{$local_part}{wxyz}{5678}{\
          9999}}"


which would be fine for a small number. You could put that option either
on the aliasfile director or the transport.

No. I can see what you are getting at here, but it wouldn't be at all
easy to make it work. The reason is that the uid is set up before the
transport is called. Therefore the external code that determines the uid
doesn't have access to the parameters of the transport.

Hmm. Wait. For cases where the file name comes from an alias or
forwarding operation this could be possible, since the file name is a
pseudo-local-part. I will put this item on the wish list.

See the debug_print generic option for directors and routers, introduced
in version 2.00.
