Hey guys,
I've got a exchange 2010 edge server which has two send connectors, one that does internet mail flow and the other which does internal to exchange 2013. Also i have a default receive connector.
Currently i have a spam filter doing unauthenticated SMTP relay to Exchange, i want to cut over to exchange edge server to do SMTP relay. The only issue i can think up is that i have a whitelist of which source IP can send directly to the internet but some devices can relay mail internally due to IT security policy. I've got a small list of source IP address that are not allowed to send external.
1.create two new receive-connectors on the edge server one that is allowed to relay both internal or external and one that canonly relay internal?
any ideas or thoughts on this subject?
Regards
Nathan
