The list of host names for which email delivery takes place locally (Sendmail
documentation calls this "class 'w'" some times, if I remember correctly).

If your hostname is foo.example.net and the `confCW_FILE' macro points to
/etc/mail/local-host-names (as it does by default), and that file contains:

    bar.example.net

Then Sendmail will try to deliver messages sent to user@bar.example.net
locally too.

You don't absolutely _have_ to put *ALL* your host names in local-host-names,
because as I wrote before, Sendmail tries to auto-discover the local host
names.  You can see this list by running Sendmail in 'test mode' and looking
at the value of '$=w' like this (pressing CTRL-D exits from 'test mode', near
the end of the following example):

# keramida@flame[13:35]/home/keramida$ /usr/libexec/sendmail/sendmail -bt
# ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
# Enter <ruleset> <address>
# > $=w
# [IPv6:::1]
# [IPv6:fe80::1]
# flame.pc
# www.pc
# mail.pc
# localhost.localdomain
# localhost
# flame
# [127.0.0.1]
# localhost.pc
# [IPv6:fe80::211:95ff:feca:e5e8]
# flame.localdomain
# freebsd.pc
