You can do it from /etc/mail/access
by setting it to:
# Check the /usr/share/doc/sendmail/README.cf file for a description
# of the format of this file. (search for access_db in that file)
# The /usr/share/doc/sendmail/README.cf is part of the sendmail-doc
# by default we allow relaying from localhost...
188.8.131.52 RELAY #your SMTP server IP
To:postmaster at yourdomain.com OK #relay OK to this address
To:root at yourdomain.com OK #relay OK to this address
To:you at yourdomain.com OK #relay OK to this address
To:yourdomain.com REJECT #then rejects any other address
When the file is correctly filled for EACH E-Mail Addres, Alias and
Domain make a:
makemap hash /etc/mail/access < /etc/mail/access
And that's it...
