Obtaining Details of Emails Blocked by Norton AntiSpam Protection

G’day Forum,

I note today that Norton AntiSpam Protection has blocked 7 incoming emails. I have been expecting a reply to emails sent 5 days ago to the same address in UK and have not received a reply. I am wondering if email from this UK source is being seen by Norton as spam, and is blocking same.

Can I obtain sender and header details of blocked email and can I over-ride blocking when required?

Regards.
