'Router' as in exim configure file, not as in Cisco, etc.

Account validity can be checked by making a query (not an actual delivery)
to the 'routers' defined in exim's configure, and is ordinarily true/valid
if *at least one* router would accept the traffic for its associated
transport.

In that sense the forwarder DOES 'have an account' at least insofar as
being associated with a valid identity you will accept traffic for,
never mind that you may not keep or store said traffic.

Default configure aside, routers may or may not exist / be configured to
include system (Unix or other) shell acounts, system aliases, 'virtual',
or any other class of accounts.

IOW, someone would have to look at the code to be certain.
