Cloud Configs for creating a secure ProtonMail Bridge system

1. Copy and paste the cloud config .yml contents where applicable for your cloud. (I make use of Hetzner Cloud, though your cloud may work without any changes necessary.)
2. In the .yml contents, specify your new Proton Mail Bridge system's hostname, and the contact email address to use with the Let's Encrypt SSL certificate registration:
   • - echo "#!/bin/bash\n/root/create-protonmail-bridge-system.sh 'proton-bridge.your-domain.com' 'you@your-domain.com'" >/root/create-protonmail-bridge-system-with-args.sh
3. Once the Proton Mail Bridge installation is complete, login to the system as root and run proton-bridge-cli. At the Proton Mail Bridge CLI prompt:
   1. Enter login and proceed with the prompts to login to your Proton Mail account.
   2. Enter info and make note of the username and password. You will need this information for your email client.
   3. Enter exit.
   4. Start the service with systemctl start proton-bridge.
4. The ProtonMail Bridge will be accessible on ports 993 (IMAPS / IMAP SSL) and 587 (SMTPS / SMTP SSL). Enjoy!
