HI Guys, I have an Exchange 2010 server and I changed the IP address on the A record for my mail server. Now relays are being refused. I didn't change any settings at all on the Exchange server, just changed the A record.
The reason I made this change was a certain company wasn't receiving our e-mails and they said our forward and reverse dns IP addresses were mismatched. I wasn't having a problem with anyone else, but I figured the change wouldn't be a big deal. Any ideas guys/gals?
