Hello @Innocent_Nwaukwa

It looks like you are trying to use ProtonMail settings for local deployment which is most likely not suitable for you/ Do you use Backendless Cloud?

You mean Bakendless default email service?
That’s what I’m using now

Hi, @Innocent_Nwaukwa

Proton Mail Bridge is a desktop application that runs locally on your computer to encrypt and route emails through Proton Mail’s servers. It is designed for use with email clients installed on the same machine, such as Thunderbird.

Backendless is a cloud-based service, which means it cannot connect to services running on your local machine (like 127.0.0.1:1025). This is why your current configuration works in Thunderbird but not in Backendless.

To send emails from Backendless through Proton Mail, you’ll need to connect directly to Proton Mail’s public SMTP servers instead of the local Bridge. Proton Mail provides an SMTP submission endpoint specifically for this purpose.

Recommended settings for Backendless:

  • SMTP host: smtp.protonmail.ch
  • Port: 587
  • Authentication method: PLAIN or LOGIN
  • Encryption: STARTTLS

Once you update your Backendless Email Settings with these values, the platform will be able to send emails using Proton Mail servers.

Kind regards,
Karyna
