Although it’s not recommended to use GoDaddy’s own email servers you can do it but have to follow some rules:
GoDaddy has a limit of 250 emails from a certain account so make sure you set up the sending limits correctly. Use this form to calculate your values.
You have to make sure the used from and reply-to address matches your domain.
On the delivery tab choose “SMTP” and insert the following:
- Server: relay-hosting.secureserver.net
- Port: 25
- Timeout: 10
- Secure Connection: none
- SMTP Auth: none
- Username and Password: empty
There are also some limitations you may beware of.
