Allowing relay using authentication

Does any one know how to change the sendmail config that HC generates to allow valid domain/user that are hosted on the Linux server to send out mail through the server? some users travel and they have to keep changing the email settings.

Also the default HC SM config (build 17)is left as an open relay and we closed by doing this http://forum.hostingcontroller.com/topic.asp?TOPIC_ID=4954 but now the users can't send mail through the server and the php mail function will not allow email for any domains that are not on the server.

Thx

add following lines in /etc/mail/sendmail.cf
F{LocalIP} /etc/mail/ip_allow
and add the ip address of the machine in the file /etc/mail/ip_allow that can use this machine for relay.
and restart sendmail service
