The keyword is "ACLs" (see the URL below). Note that one of the ways
you can do recipient checking in Exim that is particularly useful for
an email hub that does onward delivery to other servers (especially if
they have different sysadmins) is the callout check which contacts the
destination host via SMTP in order to ask it to verify the recipient. No
user database required on the hub! You can also do callout checking for
the return path, which can greatly reduce the number of bounced bounces
you have to deal with.
