I've been using Norton Internet Security for years and years. I've also had the same ISP for as many years, and I've been using MS Outlook email client for as many years. Today, I typed a reply to an email and when I clicked on 'Send' the reply closed normally, but then an error message from Norton popped up:
Email Error
451 qq temporary problem (#4.3.0)
The email details indicated it was the email reply that I just sent. But no explanation for the problem. Did the email get sent or not?
When I tried to search for 451 qq on the Norton site, no results were found.
I've never seen this error before. Should I send the email again?
