As more and more ISPs and mail service providers reject unauthenticated mail connections or unregistered mail servers, you may find that alert and ticketing emails from your Kaseya server are undelivered. These undelivered emails collect in your c:\inetpub\mailroot\badmail directory, and the most recent emails that cannot be sent are found in the c:\inetpub\mailroot\queue directory.

If you have an external email server with an account from your ISP for POP3 and SMTP, then you can use that email server as a Smart host for the Default SMTP Virtual Server. The Smarthost can be configured to use authentication, which more mail servers require now to prevent spam via anonymous mail relay.

See the attached PDF document for instructions on configuring the authentication to an email account on an external mail server which will serve as the Smart host for all outbound emails sent from your Kaseya Server.
