How to configure Email

  • From the Explorer view, choose Options, then select Email Settings. The Email Settings view displays.
  • Use the System administrator email address text box to enter one or more email addresses.
    Alert Separate multiple email addresses by commas. Note: The administrator email is used to send license error notifications. For example, this email address is used when the system MAC address changes causing the software to lose its licensing.
  • Use the Type drop-down to specify the email API and connection method. The following options are available:
    Plain Text Sends plaintext and unsecure email messages using SMTP. Only use this method when sending messages over a secure internal network.
    Uses port 25 by default.
    STARTTLS Sends email messages securely using SMTP. This method is the industry standard and should be used when ever possible. Use this option when sending SMTP messages from Microsoft Office 365 accounts.
    Uses port 587 by default.
    SSL Sends email messages securely using SMTP over a Secure Sockets Layer (SSL) channel. This option is provided for legacy email server implementations.
    Uses port 465 by default.
    Microsoft Graph Sends email securely from a Microsoft Office 365 account using Microsoft's Graph API.

SMTP Email

  • Use the Server text box to specify your email server.
  • Use the Port text box to specify your email server port.
  • Use the Username text box to enter the username to access the mail server.
    Alert To send anonymous email leave the Password field blank. If you leave the Username blank, the email server's spam engine will likely flag the messages as spam.
  • Use the Password text box to enter the password to access the email server.
  • Use the From name text box to enter the friendly From name listed in the email (e.g. Corner Bowl Server Manager).
    Alert When using a service provider, such as Amazon Simple Email Service, that requires users to first authenticate with a non-email username and password, use this field to specify both your from name and from email. For example:
    Corner Bowl Server Manager <>
