I checked open ports on the host machine, all good: ss -plnt State Recv-Q Send-Q Local Address:Port Peer Address:Port Process LIS127.0.0.1:1025 0.0.0.

without having to download the entire content. Issue: From the Docker container, I cannot connect to the SMTP server exposed by the Protonmail Bridge on the host machine. For those who want to use protonmail bridge with windows 10 native app, open it and on `add account` > `advanced internet email` use the values on the table below.ĭisclaimer: I'm a spanish user, maybe I make some mistakes on translations, but the configuration options are in the same order as the wizard.ĭisclaimer2: Don't think your email are not protected for unchecking SSL options, the bridge handles that stuff for you, mail app doesn't handle well selfsigned certificates that bridge uses for local communication. You must install, run and login to Protonmail Bridge app in the same box as your Nextcloud instance, then configure Mail server manually in NC using: IMAP Host: 127.0.0.1 IMAP Security: None IMAP Port: 1143 (or whatever your ProtonMail Bridge config says) SMTP Host: 127.0.0. It has a lot of advanced features besides supporting IMAP, POP3 and SMTP.
