Hi All
Simple prob I bet, I have exchange 2000 installed on a
2000 server, with ISA etc (sbs server I think)
Internal users send/receive emails fine.
External (remote users) also send/receive emails fine. Via
outlook using SMTP
The problem is external users, they can send emails even
if they dont enter a password, which means anyone can send
through my server! if I create a new account on my pc at
home called TEST@domain.com, and enter my exchange IP
address, I can send through my server to my hotmail
account!
AHHH this isn't good!! (open relay I think its called)
I know you can specify certain machines only to access my
SMTP protocol, but, the remote users IP addresses change
as they use dial up.
I want to make it so a password has to be entered (or
stored) on the users machine in order for them to send an
email through my exchange server.
Whats the best solution! thanks a million
