If I understood your last post correctly and you want to re-enable Norton's email protection, then do the following:
Open OE and go to Tools > Accounts > Mail.
Highlight your email account and click on 'Properties' then the 'Servers' tab.
Change the 'Incoming Mail (POP3):' to 127.0.0.1
Change the 'Account name:' to username/pop3.server.name
Note: username will be your email id and pop3.server.name is your ISP's Incoming mail (POP3) server name.
I've included a few links below that relate to your issue:

I hope this helps.
