I managed to install the docker image on an existing server with Apache as a Reverse proxy and letsencrypt certificates.
Almost everything is working good so far except I can’t setup the smtp. I have a working email server and whatever setting I use I have errors. I can connect/receive/send emails with my email clients (laptop, mobile, webmail), I can use my email server with other applications (mattermost, wordpress, etc.) but not with Rocket.Chat. My email server certificate is self signed. Looks like RC doesn’t like that but I can hardly use a Letsencrypt certificate. I tried ports 465 and 587 (both are working with my thunderbird email client), I tried smtp and smtps, ignoreTLS or not, pool or not (although I’m not sure I understand what are this 2 settings for).
Any help would be appreciated
