I've read many posts concerning Norton scanning e-mails coming in from an SSL port and find the responses from Norton not quite accurate. What I have read is that Norton will not support the scanning of e-mails coming through from an SSL port, but it will support POP3 servers. My guess is they are not banking on us being able to put 2 and 2 together.
Like what I've read concerning Verizon e-mail accounts, AT&T users also have their e-mails coming through those same POP3 SSL ports. So while the statement about Norton being able to scan POP3 servers may be true, what is not true about it is if the e-mails come through SSL ports on POP3 servers. Not only does it have a major impact on the Anti-virus feature of Norton, it also has a major effect on the Norton Anti-Spam feature by rendering them both useless.
What this raises, in my opinion, is being able to justify the cost of buying Norton Internet Security for 5 devices each year. One thing I've noticed recently is a lot of good press from security professionals concerning Windows Firewall and Windows Defender in Windows 10. While we tend to rely on Norton Identity Safe for managing passwords, since I never know if it is going to actually fill in my credentials each time I visit a site, there are products out there (i.e. RoboForm, True Key from Intel, etc.) that are actually much more reliable and have also gotten very good press. Regardless of what their management may think, their old Network Map was a very valuable tool because it was also configurable.
I have been a very long time Norton user, but one thing I've noticed is that as time has gone on, functionality has shrunk while price keeps inching up. I only have a few days left on my current subscription so maybe it is now time to seriously look at my options. It's a shame...it really did used to be an excellent product.
