The SMTP Setting allows the administrator to configure the SMTP Server Settings for ImageQuest email routing notifications and to send a test email to confirm that the settings are valid.
By default, email notifications will be sent as the IQAutoNotify user with the SMTP address appended to it (i.e. IQAutoNotify@yourserver.example.com). This can be overridden by checking the “Custom From Address” checkbox and specifying another email address. This is a requirement for certain mail servers such as Office 365.
