BTW: There is a boat load of information regarding configuring sendmail in
this README file. I have only included the relevant part to your question
below.

<README cut/paste begin>
Remember, since /etc/mail/access is a database, after creating the text
file as described below, you must use makemap to create the database
map. For example:
makemap hash /etc/mail/access < /etc/mail/access
The table itself uses e-mail addresses, domain names, and network
numbers as keys. Note that IPv6 addresses must be prefaced with "IPv6:".
For example,
[EMAIL PROTECTED] REJECT
cyberspammer.com REJECT
TLD REJECT
192.168.212 REJECT
IPv6:2002:c0a8:02c7 RELAY
IPv6:2002:c0a8:51d2::23f4 REJECT
would refuse mail from [EMAIL PROTECTED], any user from cyberspammer.com
(or any host within the cyberspammer.com domain), any host in the entire
top level domain TLD, 192.168.212.* network, and the IPv6 address
2002:c0a8:51d2::23f4. It would allow relay for the IPv6 network
2002:c0a8:02c7::/48.
The value part of the map can contain:
OK Accept mail even if other rules in the running
ruleset would reject it, for example, if the domain
name is unresolvable. "Accept" does not mean
"relay", but at most acceptance for local
recipients. That is, OK allows less than RELAY.
RELAY Accept mail addressed to the indicated domain or
received from the indicated domain for relaying
through your SMTP server. RELAY also serves as
an implicit OK for the other checks.
REJECT Reject the sender or recipient with a general
purpose message.
DISCARD Discard the message completely using the
$#discard mailer. If it is used in check_compat,
it affects only the designated recipient, not
the whole message as it does in all other cases.
This should only be used if really necessary.
SKIP This can only be used for host/domain names
and IP addresses/nets. It will abort the current
search for this entry without accepting or rejecting
it but causing the default action.
### any text where ### is an RFC 821 compliant error code and
"any text" is a message to return for the command.
The string should be quoted to avoid surprises,
e.g., sendmail may remove spaces otherwise.
This type is deprecated, use one the two
ERROR: entries below instead.
ERROR:### any text
as above, but useful to mark error messages as such.
ERROR:D.S.N:### any text
where D.S.N is an RFC 1893 compliant error code
and the rest as above.
For example:
cyberspammer.com ERROR:550 "We don't accept mail from
spammers"
okay.cyberspammer.com OK
sendmail.org RELAY
128.32 RELAY
IPv6:1:2:3:4:5:6:7 RELAY
[127.0.0.3] OK
[IPv6:1:2:3:4:5:6:7:8] OK
would accept mail from okay.cyberspammer.com, but would reject mail from
all other hosts at cyberspammer.com with the indicated message. It would
allow relaying mail from and to any hosts in the sendmail.org domain, and
allow relaying from the 128.32.*.* network and the IPv6 1:2:3:4:5:6:7:*
network. The latter two entries are for checks against ${client_name} if
the IP address doesn't resolve to a hostname (or is considered as "may be
forged"). That is, using square brackets means these are host names,
not network numbers.
