Try this first
- Choose between O365 SMTP relay, third-party (SendGrid), or your own relay
- Configure the device with SMTP server, port 587, STARTTLS
- Use a service account, not a personal account
- SPF: add the relay IP or include to your SPF record
When to bring us in
For many devices, dedicated relay with IP whitelist beats spreading credentials.
