SMTP connection error message always shows port 25

[pkelbert]

Even after changing SMTP settings, when I try to register a new user Codenvy always shows error connection on port 25:

Could not connect to SMTP host: smtp.mailtrap.io, port: 25

Expected behavior:

The port number should be the same set in CODENVY_MAIL_HOST_PORT, eg:

Could not connect to SMTP host: smtp.mailtrap.io, port: 465

Reproduction Steps:

1. Start Codenvy with an empty data folder: docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock -v ~/codenvy1:/data codenvy/cli start
2. Stop Codenvy: docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock -v ~/codenvy1:/data codenvy/cli stop --skip:graceful.
3. Edit codenvy.env (these only two lines are enough for reproducing the error):
   • CODENVY_SMTP_HOST=smtp.mailtrap.io
   • CODENVY_SMTP_HOST_PORT=465
4. Start Codenvy again poiting to same data folder: docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock -v ~/codenvy1:/data codenvy/cli start
5. Access http://localhost on a browser.
6. Click on Create a New Account.
