Configuration path
Choose a custom SMTP provider in DSM notification settings and configure the connected mailbox as sender.
- 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.
- Review Hyper Backup, storage, certificate, and security rules separately.
- Use a dedicated smtpify365 connection for the NAS.
- Retest after DSM upgrades.
