If I run this command to make sure there is no open relay on my exchange 2010 server, do i have to run it for all receive connectors or just the default?
There are 4 other rec connectors setup also.

Get-ReceiveConnector “ReceiveConnectorName” | Remove-ADPermission -User “NT AUTHORITY\ANONYMOUS LOGON” -ExtendedRights “ms-Exch-SMTP-Accept-Any-Recipient”

Don’t forget to replace ReceiveConnectorName with the name of your own receive connector.

You need to run this command for every receive connector you want To Close An Open Relay

You can verify that your server don't have open relay with many web pages.

Is there anyway that I can check each connector since there are 6 total, to make sure they are not configured as an open replay with some permissions or some other setting on each connector via the EMC?

The exchange server I am working on is 2010. Does the same apply for 2010 as 2007 or is it different?
