Several:

- The simplest, presuming you have a 'conventional' system/alias router,
is to add an alias entry to /etc/aliases (or wherever...), of the form:

wbh: wbh, wbh@???, wbh@???

(where 'wbh' is either a shell-account holder AND/OR a member of the
virtual user group, such as wbh@???, on that box)


CAVEAT:

- If running virtual-hosting, and there could be more than one 'wbh'
locally OR in the virtual table, OR any other router, the 'wbh:' will do
the expected, which may not be the desired..

;-)


Ergo:

- A more code-complex, but fine-grain-controllable approach would be to
use an 'unseen' router with whatever special conditions suit your goals.
This can insure acting on the specific <domain>.<tld> in a non-ambiguous
manner.

The second section - after the 'unseen' - would resemble comon code
snippets for forwarder routers.

Selecting the conditions depends on your needs, but they can be
per-user, per-domain, or driven by an acl_m flag or X-header - even
time-of-day, which Exim has internal access to, or phase of the moon,
which it can read from an external source...
