Proxmox VE

Send cluster, backup, and host notifications.

Create an SMTP notification target and route selected events to it using notification matchers.

Configuration path

Create an SMTP notification target and route selected events to it using notification matchers.

  • Server: the hostname displayed by smtpify365
  • Port: 587
  • Connection security: STARTTLS
  • Authentication: required, using the generated SMTP username and one-time password
  • Envelope sender: the Microsoft 365 mailbox that authorized the connection

Product-specific checks

Complete the application test and then trigger one real workflow to verify that configuration, event rules, and transport all work together.

  • A target alone does not select events.
  • Test DNS and port 587 from the relevant cluster node.
  • Separate urgent failures from routine summaries.
