I use MXroute for low volume, automated email from software and devices. Having unlimited mailboxes (one per device) and super low (configurable), per mailbox quotas is a better solution than the expensive providers have. Office 365 is brutal for sending from devices. In fact it’s impossible with security defaults (more like overrides) enforcing 2FA and one of their supported options is literally (I’m not joking here) to use another mail server that’s not Office 365. https://docs.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365#use-your-own-email-server-to-send-email-from-multifunction-devices-and-applications https://docs.microsoft.com/en-us/exchange/mail-flow-best-pra...
