Ok, I have an Exchange 2007 server.
I am using an external antivirus/spam solution "Postini",
I am configured to send outbound mail through postini as well. This is configured as a smart host.
I need to setup the exchange server to
Allow Anonymous Access from the internal network. For other servers, scanners, alerts to relay anonymousely.
I need to allow postini to relay anonymousely through this connector. I need to specify their subnet.
I want to allow internet users to authenticate for smtp and pop3. - Pop3 portion is working properly.
All anonymous internet users cannot relay.
Can this be done with one receive connector or what?
