I did not find any articles there on how to setup a manual configuration on Apple Mail. I then went to the website of ProtonMail to check their knowledge base. So it turns out that the profile which is created with the ProtonMail Bridge app on your MacBook does not install a SMTP server configuration for Apple Mail.

Very nice! Then I wanted to test if I could send emails from Apple Mail but I just got an error that there was no SMTP server configured….what now? Manual setup SMTP server settings Immediately my ProtonMail mails and folders started to show up in Apple Mail. To make sure that everything works I rebooted my MacBook before starting Apple Mail. This profile then automatically configures Apple Mail. Basically ProtonMail Bridge creates a profile which you have to accept and install. Anyway, after installing the ProtonMail Bridge app I followed their manuals for setting up Apple Mail. I am hoping that they eventually develop a dedicated app for macOS just like the app on iOS (I hope you read this ProtonMail :)). Since I am on macOS I use Apple Mail because I fulfils my every need for a simple straight-forward mail client. I must say I love their webmail solution but I still prefer using a dedicated mail app on my MacBook.

The app is compatible with most email clients supporting IMAP and SMTP protocols. Bridge runs in the background by seamlessly encrypting and decrypting messages as they enter and leave your computer. ProtonMail Bridge is an application available to all paid users that enables the integration of your ProtonMail account with popular email clients, such as Microsoft Outlook, Mozilla Thunderbird, or Apple Mail. Let me quote them because it basically explains it all: If you found this post you most likely already know what ProtonMail Bridge is. I am happy to pay ProtonMail and have my mind at ease. You can argue why not self host? Well for my personal situation I think setting up and maintaining a mailserver is just not worth my time. Online privacy is something I am very concerned with and that’s why it was a logical move for me to switch to ProtonMail. In this post I will show you how to properly configure ProtonMail Bridge SMTP config with Apple Mail on macOS Big Sur. Reading Time: 4 minutes ProtonMail with ProtonMail bridge
