- SMTP host: IP address of your SMTP server ( SMSEagle’s IP at our example)
 - Sender’s email address: desired sender email
 - Mark the checkbox “Send test email”
 - Enter Recipient email address in format mobilenumber@smseagle_fqdn
 - Test message sent to mobilenumber@smseagle_ip will work as a test, but actual alerts will only accept FQDN option.
