Configure your inbound server(s) to be primary MX for your domain.  Set
your local domain in the "local-host-names" file, and in your sendmail.mc:

define(`MAIL_HUB', `your.inside.server.com.')

This will allow you to use the access database, yet have local delivery
on another machine.

And your access file, instead of RELAY, change it to OK, as follows

aaa at yourdomain.com              OK
bbb at yourdomain.com              OK
ccc at yourdomamain.com            OK

...


zzz at yourdomain.com              OK
To:yourdomain.com               ERROR:"550 no such user here"
