Hello,
my users reported, that the forgot password function is not working. They get the error message
Error trying to send email: Mail from command failed - 501. The following error message is printed into the logs. No other issues are found.

Error: 139676799047488:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number:../deps/openssl/openssl/ssl/s3_pkt.c:365:

I use rocket chat inside a docker and this container is behind a proxy. Maybe this generates the issue.
Proxy Config is:

# REQUIRES:  a2enmod proxy
# REQUIRES:  a2enmod proxy_wstunnel
        <Location />
            Require all granted
            Options -Indexes
        </Location>

        ProxyPass /websocket ws://localhost:3000/websocket
        ProxyPassMatch ^/sockjs/(.*)/websocket ws://localhost:3000/sockjs/$1/websocket
        ProxyRequests Off
        ProxyPass / http://127.0.0.1:3000/
        ProxyPassReverse / http://127.0.0.1:3000/

For SMTP server, I use port 465 and the test mail is working.

I tested the docker container without a reverse proxy in between. The same error occures. This means the proxy is not the reason for this error.
