We have [blogged about this previously](https://www.exchangedefender.com/blog/2018/05/exchangedefender-iot-relay-accounts/) and the demand for this service really surprised us – so we’re rolling with the production and adding all the new features into the beta product as the applications for this service are quite extensive. To sum it up: ### ExchangeDefender's IoT Email Relay Service ExchangeDefender IoT Email Relay Service is a custom email smarthost (outbound relay) designed specifically for Internet of Things devices and services to securely dispatch realtime email alerts. Feature-wise: \- XD IoT Relay assigns every device has it’s own account/credentials so if one device is compromised the email capabilities of others aren’t impacted. \- XD IoT Relay is secure permitting traffic only via TLS/SSL SMTP protocol to assure security credentials cannot be *sniffed* on the network. \- XD IoT Relay allows dynamic IP ranges, allowing for cell/4G/LTE devices and sensors with remote/unsecure network connectivity to relay alerts. \- XD IoT Relay is compatible with every device that can send out email via SMTP/SSL (should be all of them) and is backed by our support and automated throttle management (in the event of an infection) ### New feature is available in the ExchangeDefender admin [portal](https://admin.exchangedefender.com) under **Domain Admin > Accounts > IoT Accounts**. Simply add a new account for each device you wish to have relay rights for (they are free for now) and configure your device to relay through **outbound-auth.exchangedefender.com**. Our service is globally redundant (no single point of failure) and is under our SPF/DMARC announced range. ![iot_account_v1-1.png](https://storage.services.exchangedefender.network/exchangedefender-blog/blog/2018/05/iot_account_v1-1.png) We will be blogging more about this feature as we develop it and get a better handle of how it’s used but the feedback so far has been very positive and constructive. The biggest surprise (read: shock) is the level of unreliability of some of these devices/sensors and their rather infant API/app development – but they all know how to send email so many of our partners are looking to us to help fill the void between these devices/sensors going dark/offline and production email notification service. Many of our partners also looked to use this for printers, blogs, contact forms and a seemingly endless set of services that a remote ISP should be providing but they don’t – so when it comes to business and email people come to ExchangeDefender.
