DadsonFire.club. On GoDaddy, has worked fine for years and stopped today! Godaddy don't have a clue about it.

mail.dadsonfire.club
Port 587 TLS
OK, you are hosted on GoDaddy. Did you follow my instructions and logged into cPanel? That way you can find the host name that will work on gmail. Also, you gmail setting are no longer functional. You need to use
SMTP server: check host name from your cPanel
Port: 465
SSL
The problem is in gmail. They changed the way they check SSL certificates, And GoDaddy does not have a functional SSL certificate for the reverse DNS names of their shared hosting servers. You reverse DNS host name is ip-160-153-129-24.ip.secureserver.net and it does not have a valid SSL certificate. Here is the full explanation.

Hmm, strange. What host name are you seeing in your cPanel, the web address in your web browser? What is the whole URL?

Try these:
  • SMTP server: n3plcpnl0046.prod.ams3.secureserver.net
  • Login: Your email address, for example contact@webseodesigners.com
  • Password: Use the email account’s password, the same you use when you check your email using GoDaddy webmail.
  • Port: 465
  • Select Secured connection using SSL
If that will not work, please make sure you are using cPanel email, not workspace or office 365 etc.

Then the problem has to be in your cPanel settings, login or password, if the SMTP server name is the one I gave you.
