I'm troubleshooting a RDNS issue and cant figure out if my 2007 server is doing RDNS checks. Has this setting been removed on 2007? I cant figure out where this checkbox is on 2007.

Exchange 2003 could do reverse DNS checks, it was unable to reject email on that basis. Exchange 2007 reverse DNS checks are done through the antispam options, which are only enabled by default on Edge. If you have a single server then they are not enabled by default. If the script has been run to install them then you will have the antispam tab on the Hub Transport properties.
