I have recently installed Exchange 2007 SP1 -- and am having difficulty getting the Receive Connectors configured correctly. The default connector is configured for 'any' IP and Permission groups Exchange Users and Exchange Servers. the default connector authenication accepts TLS, Basic Authenication with TLS, Exchange Server authenication, and Integrated Windows authenication. I have a custom connector with Permission groups - Exchange users, Exchange Servers, and Anonymous Users -- which accepts from only specifically specified IPs. My problem is that applications, UPSs, etc. that try to email using our own Exchange accounts do not work -- unless I specify their IP and let them work anonymously. How do I configure it so that our own exchange accounts can email through the default connector. One particular apps for instance, lets you specify the 'From:' & 'To:' accounts -- if both are our own Exchange accounts and I'm logged in as the 'From:' -- it doesn't work. I receive "421 4.3.2 Service not available, closing transmission channel" in the log file.
Thanks for your help.
