Hi @mdev_mdev. Thanks for being part of GoDaddy Community! It's true that you would not be able to send email from a hosting plan with GoDaddy using an SMTP server other than relay-hosting.secureserver.net. I'd recommend taking a look at the suggestions on this post to help with mail delivery issues. Hope this helps.
