Direct messages are visible in docker logs

[AlvaroBrey]

Title says it all. I was checking docker logs when I saw that all messages on the rocketchat instance are logged to stdout in mail format. To be specific, messages are something like this:

rocketchat_1          | ====== BEGIN MAIL #251 ======
rocketchat_1          | (Mail not sent; to enable sending, set the MAIL_URL environment variable.)
rocketchat_1          | Content-Type: text/html; charset=utf-8
rocketchat_1          | To: [redacted for issue]
rocketchat_1          | Subject: [chat.myserver.com] You have been direct messaged by [redacted for issue]
...
[some HTML body with the text of the message in it]
...
rocketchat_1          | ====== END MAIL #251 ======

Is there any way to stop this from happening?

As a workaround for now, we've configured SMTP and asked users to disable email notifications. This is not an ideal solution however.
