How to cancel email forwarding?

[mournetraining]

I set up email forwarding for my primary account in the manage services area but now I can't turn it off. I can change the forwarding address but there is no option to stop. In a previous thread a 'none' option was mentioned but this does not appear. Any ideas would be greatly appreciated.

I think there is a recall option available for forwarded emails, though I don't remember where I actually seen it.
