Hi,


.........
By default, the Sendmail mail transport agent (MTA) does not accept network 
connections from any host other than the local computer. If you want to 
configure Sendmail as a server for other clients, you must edit 
/etc/mail/sendmail.mc and change the DAEMON_OPTIONS line to also listen on 
network devices (or comment out this option entirely using the dnl comment 
delimiter). You must then regenerate /etc/mail/sendmail.cf by running the 
following command (as root):

      make -C /etc/mail

      Note that you must have the sendmail-cf package installed for this to 
work.


Ciao,
Gio
