Do I need to keep the .local email address in AD or in the Recipient Policy for any reason?
Posted on 2006-11-10
This is for Exchange 2000 on Windows 2000 servers. I want to delete these .local email addresses from all user accounts in AD so there is no chance that a .local email address is used when an employee sends an email to external recipients and cc’s an employee and a .local email address ends up getting sent out across the Internet making it impossible for those external recipients to reply to those employees who’s .local email address were used instead of their .org email address.
So, I just want to know what the .local addresses are used for and what, if any, consequences there would be if I deleted the .local addresses altogether from the Exchange Recipient Policy.
I’ve actually already deleted the .local email address from the recipient policy a few weeks ago and that solved the problem. But the .local addresses were added back into the Recipient Policy by another admin because he was/is under the impression that a local application needs the .local addresses. I think I’ve proved that the application in question can use the .org email addresses just fine.
One person on EE suggested deleting the .local addresses from the Recipient Policy and said that his company always sets up new domains without the .local addresses. I can see that if you don’t set up a domain with the .local suffix (or whatever it’s called) then there is no reason to be concerned with deleting the .local addresses from the Recipient Policy, if it even exists in such a case. But another person yesterday suggested that I should not delete the .local address from the Recipient Policy because if the domain was built with the .local suffix then removing the .local address form the Recipient Policy could cause Exchange or AD to fail in some ways.
After I deleted the .local address from the Recipient Policy a few weeks ago, I did not notice any problems with Exchange or AD. So I’m curious now as to exactly what these .local addresses are used for and what am I going to mess up if I delete the .local address from the Recipient Policy. Thanks.
