Telnet to SMTP Vulnerability- disable anonymous user

I have a vulnerability that allows spoofing through telnetting SMTP on our exchange 2010 through the WAN interface(smtp public address)
. If I disable anonymous user, would I need to create transport connectors for internal IP addresses that uses SMTP for emailing (apc, temperature, scanners)?
