How to remove the address of the internal SMTP server in Exchange 2010

Hello, I used the following command when I was trying to enable my anti-spam filter in Exchange 2010

Set-TransportConfig -InternalSMTPServers @{Add="10.0.1.10","10.80.1.34"}  - I only wanted to add the internal address of 10.80.1.34 but I also added the 10.0.1.10 address -

What cmdlet can I use to remove the 10.0.1.10 ip address - please help me with the exact script I need to run to remove that ip address?

Thanks
