TopicEmail Server Connection Problems
If you send an email, your recipient’s ISP may display an error message if it thinks the email contains spam or sent an attachment that’s larger than the ISP permits. That error message says, “Your email was unable to send because the connection to mail server was interrupted.” You could also see the message if the email address you entered is incorrect or doesn’t exist. Resolve the problem by running a full Norton system scan and then running LiveUpdate. If that doesn’t fix things, contact your ISP for additional help.
If your ISP rejects any email, you get the error message as Norton antivirus Email protection feature interacts and displays such a message. You can turn off this email protection by following the below steps:
- Go to settings, ( check if you are using Norton antivirus or Norton internet security product)
- Then click on the network and hit the message protection option
