POP3 TCP:110 (incoming mail)
Uncomment pop3 service in /etc/inetd.conf:

	pop3  stream  tcp  nowait  root  /usr/sbin/popa3d  popa3d

Restart inetd: as root, run:

	# kill -HUP `cat /var/run/inetd.pid` 

SMTP TCP:25 (outgoing mail)
Edit localhost.cf instead of sendmail.cf

      # makemap hash /etc/mail/virtusertable.db < /etc/mail/virtusertable
      # makemap hash /etc/mail/access.db < /etc/mail/access

You'll need to rebuild these databases and restart sendmail each time you 
make changes to the virtusertable or access files.

If you wish to query the hosts file before DNS servers, create a /etc/mail/service.switch file which contains the following line: 

     hosts       files dns

If you wish to query ONLY the hosts file, use the following: 
     hosts       files
