Domain name in ADS is not .local - instead it matches the Internet DNS - causing random problems/bounces?
Posted on 2008-10-20
If you have an Exchange Server, that's used as a internal LAN server + Exchange on the Internet, it's usually configured with a .local ADS set up.. but what if a server is configured for ADS and it matches the Internet FQDN and there is no .local - only "server.domain.com" in ADS and Exchange?
There seems to be strange, random bounce issues... 95% of mail flows fine, but sometimes if an outside person "Replies" to a message sent by an internal user, it bounces with '504 Need to Authenticate First".. I suspect it has something to do with the DNS set up and Active Directory..? Any insight into this kind of set up?
