Important
The default sendmail.cf file does not allow Sendmail to accept network
connections from any host other than the local computer. To configure
Sendmail as a server for other clients, edit the /etc/mail/sendmail.mc
file, and either change the address specified in the Addr= option of
the DAEMON_OPTIONS directive from 127.0.0.1 to the IP address of an
active network device or comment out the DAEMON_OPTIONS directive all
together by placing dnl at the beginning of the line. When finished,
regenerate /etc/mail/sendmail.cf by executing the following command:
m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
