I've setup new hosting with a new domain which does have SSL on it.
I've sent some test emails to my Gmail account to make sure everything is working.
I've waited sometime before doing this so I know things would be fully setup after starting a new host.
I've received emails sent via webmail app/outlook to my Gmail however I can't receive emails from anyone.
I did receive a message.
Your message couldn't be delivered to admin@... because the remote server is misconfigured. See technical details below for more information.
However, I've never had to actually set up anything after configuring the settings at the beginning from GoDaddy.
