This Document is to provide a quick overview on how to setup your SMTP accounts for your webforms, devices (printers, scanners, etc) and third-party mailing applications on our new IoT Connector. The purpose of the connector is to provide you with an easy to use network that simply gives you access to relay such devices and applications through our networks without any hang-ups.

Simply provide the device/application with an email address and the Username and Password and you should be good to go. Please keep in mind that the system cannot be used with third party Hosting companies or for abuse (SPAM, Mass mailing).

IoT Accounts

ExchangeDefender strongly encourages domain / organization administrators to create an IoT account for every device or service on the network. If one of the devices or services gets compromised (common IoT issue) they will have free access to relay mail and ExchangeDefender aggressively shuts down abuse. Because IoT devices tend to have complex configuration processes, changing the password on multiple devices should be avoided at all cost by setting up an account for each device. For this reason alone, ExchangeDefender IoT accounts are free of charge.

  • Username & Password - ExchangeDefender randomly generates the username and password for each device.
  • Description - Device or service description.
  • Disclaimers - ExchangeDefender requires strict compliance to assure security of our platform, asking you not to use the accounts for commercial/SPAM purposes or put the credentials on shared systems (WordPress blogs/forms)

ExchangeDefender IoT devices are required to relay through the following server: which is load balanced across multiple data centers for redundancy. If your ISP allows you to use port 25 (even most business connection ISPs require special permission) you can use port 25 with TLS/SSL. If you cannot use port 25, please try port 2525.
