Port 25 automatically resetting

Thank you in advance for any responses to this....

I have Outlook 2003 with SP3 running on Windows XP with SP2.

I recently setup my Outlook to run email with Google's POP3 Gmail.
According to Gmail, the setting should have POP3 set to:

-POP3 Port 995 with SSL
-SMTP Port 465 with SSL

I did this and everything works GREAT!

However, after a little while (sometimes minutes, sometimes days), my email
stops working with the SMTP and I get the message that my ISP does not
support SSL Encrypted SMTP. This is strange because it WAS working fine.

After some research, I discovered that the Outlook program spontaneously was
resetting the SMTP port to port 25!

I tried to change it back to port 465, but it didn't work. I looked online
and there was a suggestion to delete that email account and recreate it. I
did this and it worked fine....UNTIL Outlook reset the port spontaneously to
port 25 again!!!

Why does outlook keep resetting the SMTP port to port 25 for this email
account?

I have Norton Internet Security version 15.5.0.23 (current) running. I
can't imagine NIS to be doing this, but I have no idea?

Help?
