Exchange 2007 Recive Connector

[HMCTech]

I think I have made a mistake by trying to add a new recive connector to exchange 2007. To use for sharepoint incoming mail. However when I went into Server configuration > Hub Transport > New Recieve Connectory. I went through the wizard Gave it a name of "test" for Internal, left the IP addresses at the default 0.0.0.0 - 255.255.255.255 then clicked new.

 

Since then I have had problems with things like photocopiers that send to email can no longer connect to the exchange box using the fqdn only the IP address. And a few little glitches. Is there a way to reverse these new connectors?
