Registering Authsmtp Exemptions

This article explains how to register an IP address associated with a mail client for an exemption to the requirement to use authenticated SMTP.

In most cases, mail clients should be configured to use our authenticated SMTP relay,, for outbound mail. Some applications are unable to use authenticated SMTP.

To register for an authenticated SMTP exemption, please email your request to and include the following:

  1. Contact information
  2. IP addresses of devices in question
  3. Brief description of the device/application

You should hear back within 1 or 2 business days whether your exemption has been approved. Once your exemption is approved, then you may configure your application to use as an outbound SMTP relay.

Things to note:

  1. This process only registers with respect to authenticated SMTP. If you have an application or departmental mail server which you would like to have whitelisted in the central anti-spam service, contact with details about the service you need whitelisted.
  2. IT Services may preemptively revoke or refuse an exemption if there are signs of abuse or illicit email activity on a given host.
