Why does yahoo reject my email address as not valid?

When I signed up for yahoo I used my email address and it is in my profile but when I use it to try to sign up for a group I get an error message that says it is "not valid".

Update:

yes why is it rejecting my email address? It is valid, it is the one I signed up with but when I tried to use it for the group I joined it refused it as not valid.
