Add POP3 and SMTP ports to Protected Ports

Your Norton product automatically protects the default POP3 and SMTP ports to protect your email program from viruses and other security threats.

Norton supports all email accounts that use non-SSL POP3 and SMTP communication protocols and does not support SSL-encrypted email ports. Your Norton product also scans all incoming and all outgoing email messages.

To ensure email protection, we recommend that you check the POP3 and SMTP port numbers for your email program. If your email program does not use the default port numbers, you must manually add the port numbers to the Protected Ports window. This helps protect your email program from viruses and other security threats.

If the port numbers of your email program are not added to the Protected Ports window, your email program is not protected. Your Internet service provider (ISP) provides you the port numbers for your email program.

You can add only the port numbers that are not assigned to any other protocols by Internet Assigned Numbers Authority (IANA). The standard ports that are assigned to other protocols by IANA are blocked. For more information, see IANA website.
