@MichelleShaw NowTV don’t supply email accounts, therefore they don’t have SMTP servers. You’ll have to keep using your existing email account and its associated servers. If you don’t have, or can no longer use, an existing email account, I’d recommend Gmail or Microsoft Outlook both of which I use.
I use Outlook that requires an incoming and outgoing server settings.
My incoming is obviously the mail provider, my outgoing smtp has been provided by the isp.
My last one was smtp.talk.net
Every major isp has these settings, and I'm now unable to send mail out without having to go through the webmail function which is not always practical.
