If your configuring your email client or setting up your application to use SMTP authentication, we highly recommend using SSL. However, please keep in mind that you can’t use "mail.domain.com" unless you have a SSL already setup specifically for that sub-domain.
You should configure your email clients and applications to use the server's hostname instead on port 465 (for SSL) or 587 (for TLS). You can find your server's hostname in the welcome email our billing system sent to you when you first setup your web hosting account.
Here's a quick example of what you may need to configure when setting up SMTP authentication in your application.
host = "your-servers-hostname"
port = "465" (for SSL) or "587" (for TLS)
username = "firstname.lastname@example.org"
password = "your-email-account-password"
If you have any issues getting SMTP authentication setup, please contact support and we’ll be happy to help.
