I've been dealing with several problems trying to stamp out the open relay issues and I've got them taken care of. However, if I gotot the Connection button under the Access Tab of SMTP Properties, it's set to allow all except listed below. I set it to "Only the Items Listed" (just like Relay) and I can no longer receive inbound emails from the internet. Viewing the Help Screens is not helping.
Can you all tell me what it's suppose to be used for and how the standard way of setting it is? I'm concerned that I may still get relay if I don't lock this down. Am I right?
Thank you for your time
