Hi!

Can you please check this answer?

Make Rocketchat use certificate for secured SMTP server

Hi! I was checking the source code for your question, and searching for MAIL_URL I found this: I think the best you can get right now is a mix and match of the following options: rocketchat: ... environment: - MAIL_URL=smtps://user:password@smtp_server:25&secure=false&ignoreTLS=true One could work around this requirement by setting up an smtp relay that will use the provided certificate and provide a smtp server that will work with Rocket.Chat.

TL;DR
I think you can only get a mix and match of the following configurations, at your docker:

environment: 
  - MAIL_URL=smtp://user:password@smtp_server:smtp_port&secure=false&ignoreTLS=true
