I'm a Postfix user myself (using transport table/maps) however if my
understanding is correct a sendmail "mailertable" entry might just do
the trick.


# Add me to /etc/mail/mailertable and issue a "makemap
# hash /etc/mail/mailertable < /etc/mail/mailertable"
#
# This will send all mail for @charter.net via the ISP SMTP relay while
# leaving other mail to be sent directly as per normal config

charter.net	smtp:[my.isp.smtp.relay]
