Im having a bit of trouble trying to configure smtp so Im not a open relay
to send email externally but also internally too.

I have a server setup for users on the outside to send email through it, but
im trying to configure it so that everyone needs to do smtp authentication
except 1 ip range. Is this possible?

Users do need to smtp auth to send email through it, but the biggest problem
is spammers can connect to it and spam our company (to send to our local
domain you dont need to smtp auth).

thanks in advance.
William
