This should be a temporary delivery issue. Is this a new problem with one message, or have you been getting this for a while every time you attempt to send anything? Try resending later. The 451 error message, although displayed by Norton, actually comes from your ISP.

See the following Rogers support page. Access to the Execulink servers through your Rogers account may be blocked as a measure to prevent the sending of spam. Generally, you must log in to your account using your ISP's service, rather than through another provider, in order to send mail though your ISP's servers.

I can send out my email fine if I uninstall Norton. Makes me think it is a setting in Norton??
Try turning off Outgoing Email Scanning (you can stop the Fix Now alerts by hovering your mouse over "Email Protection" in the main Norton window chosing "Ignore"). Can you confirm that the email messages are actually arriving at their destinations with Norton removed, rather than that you are just no longer seeing an error message? I still think an ISP issue is more likely, but sometimes Norton does cause some issues that are hard to figure out. Keep experimenting.
