I have a Sendmail server server sitting in my DMZ for POP users. This box is using SASL for SMTP. It forwards to the Exchange server. I've tried to configure the IMS to accept for relay only those messages being passed to it from the Sendmail box.. ("Hosts and clients with these IP addresses" is configured with the IP of the Sendmail server.) It does not work. I get a 550 from the Exchange box. Maybe I'm doing something wrong?

I was able to open up the IMS to accept from just certain IP addresses and from authenticated users.

Our final resolution was to have a invisible SMTP server. > Ali - you HAVE to allow relaying for POP3 to external addresses to work, because your POP users have to use your IMS as a RELAY server for outbound mail. The trick is closing the holes so that spammers can't use your server. > > On the routing restrictions page: turn on "Hosts and Clients that Successfully Authenticate" then tell your POP users to set their client to pass their authentication to their outbound server.
