wireless error????

Are you using your wireless connection to surf at the moment?
Is it just outgoing e-mail that's not working?
Can you receive mail?
If the answer to the above is yes, it's highly unlikely to be your wireless but more like a configuration error with your e-mail.
Make sure that any server settings requiring authentication or user name and password are disabled for your outgoing server (assuming it's relay.plus.net).  (I take it you *are* connecting via PlusNet as you can't use the outgoing server from another ISP, you'd have to use theirs).
Which e-mail client are you using?
Have you tried connecting an ethernet cable and disabling the wireless on your PC - can you send mail then?
