Good day! I know that Digital Ocean recommends to use external email services and I want to know how to do it properly. I want to know how to implement my proton account into my droplet - (Linux based server,Ubuntu 20.04) in order to get external SMTP server. I try to put SMTP credentials for CMS on the Linux server that I get from ProtonMailBridge on my computer (Windows 10) but it doesn’t work. I entered SMTP hostname (both 127.0.0.1 and mail.protonmail.ch), port, username, password) but got fsockopen(): unable to connect to … As far as I understand I need to install ProtonMailBridge on Linux server, then log in my account on this server, get SMTP credentials and then enter them on CMS as I truly get proton SMTP server on the Linux server. Could you explain me if my guess is right? Thanks in advance.
