Netgear MR814 and MA101 errors with Outlook Express 6

I'm trying to configure my second PC running WIN98 SE 4.10.2222 A and
OUTLOOK EXPRESS 6. Wireless connection seems fine, I can retrieve
emails but cannot send. Using Comcast and error is "Server
smtp.comcast.net, Protocol SMTP, Port 25, Secure (SSL); No Socket
Error 10065, Error Number 0x800CCC0E"

I'm running Norton Internet Security and when I disable it, I can send
emails.

Anyone have similar situation. I've searched NG but cannot find
anything.

Thanks.
