This is right out of the box except I commented out the local DAEMON. > ---- looks ok I generally dnl accept_unresolvable_domains (though this hardly stops spam anymore) set up authentication (but that is beyond the scope of your question) You must ... 1 - indicate what domains that you want to accept email for... - edit /etc/mail/local-host-names (dns must point mx for the local-host-hames to this machine for this to work) 2 - decide if you want to relay mail - edit /etc/mail/access (i.e. add 192.168.1 RELAY) to allow the computers on the local network in the 192.168.1.0/255.255.255.0 range to be able to relay outgoing mail 3 - generate the new sendmail.cf file - m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf 4 - restart sendmail - service sendmail stop - service sendmail start Craig
