If you have a static IP address (or DHCP with a very long lease)
then it is ESSENTIAL!
I get relay attempts on my mail servers every single day.
I'd hate to think what they would do if they found my mail servers
open to relaying!>> Then

>To enable an IP address to relay throught your sendmail daemon
to add the line:a.b.c.d RELAY
to /etc/mail/access
then in /etc/mail type the command:make
then sendmail will automatically allow relaying from that IP
(you don't need to restart sendmail)you would normally put into the file your local IP addresses
e.g. if you use 192.168.0.x for your local IP addresses192.168.0 RELAY
