Product manual

Norton Internet Security lets you manually configure
your POP3 and SMTP email ports for email protection.
Typically, your Internet service provider (ISP) provides
you the port numbers for your email program. If the
SMTP and POP3 port numbers for your email program
are different from the default port numbers, you must
configure Norton Internet Security.
To ensure email protection, Symantec recommends
that you check the POP3 and SMTP port numbers for
your email program. If they are not the default ports,
add them to the Protected Ports window. To configure
the Protected Ports Settings option, go to the Norton
Internet Security main window, and then click Settings
> Network > Message Protection > Protected Port
Settings > Configure.
If you do not want Norton Internet Security to protect
a port, you can remove the port from the Protected
Ports window.
w
You cannot remove the default SMTP port 25 and POP3
port 110. Norton Internet Security automatically
protects these default ports.
Adding POP3 and SMTP ports to Protected Ports
Norton Internet Security supports all email programs
that use POP3 and SMTP communication protocols
with default ports. However, if your email program is
not configured with the default ports, you can manually
configure your POP3 and SMTP email ports.
To ensure email protection, the POP3 and SMTP port
numbers must be protected. If the POP3 and SMTP port
numbers are not the default ports, Symantec
recommends that you add the port numbers to the
Protected Ports window.
To add POP3 and SMTP ports to Protected Ports
