Mail being sent to be is being returned to sender

I was told that messages being sent to me are being returned. Could this be something in the settings of Avast?

Hi Linda…

I would say this is very unlikely. You might want to contact your ISP to see if there are any problems with your account. :slight_smile:

Best Regards…

Thanks, will do that
