Wrong URL in password recovery email

[vitoyucepi]

Actual behaviour

Password restoration email has wrong url that ignores port.
In my case I'm running kanboard on http://localhost:8080. It's a local development version in docker.
URL in email looks like
http://localhost/forgot-password/change/ea6e1fffe4945e2ff4eae4d4cf0eb52c4224bad171e481cf77e0f1099957c9

Expected behaviour

URL in email should look like
http://localhost:8080/forgot-password/change/ea6e1fffe4945e2ff4eae4d4cf0eb52c4224bad171e481cf77e0f1099957c9

Steps to reproduce

docker-compose:

version: "3.8"
services:
  web:
    image: "kanboard/kanboard:${KANBOARD_VERSION}"
    ports:
      - "127.0.0.1:8080:80"
    volumes:
      - kanboard_data:/var/www/app/data
      - kanboard_plugins:/var/www/app/plugins
      - kanboard_ssl:/etc/nginx/ssl
    env_file:
      - postgres.env
      - kanboard.env
  db:
    image: "postgres:${POSTGRES_VERSION}"
    volumes:
      - db_data:/var/lib/postgresql/data
    env_file:
      - postgres.env
    environment:
      TZ: ${TZ}

volumes:
  kanboard_data: {}
  kanboard_plugins: {}
  kanboard_ssl: {}
  db_data: {}

kanboard.env

MAIL_TRANSPORT="smtp"
MAIL_SMTP_HOSTNAME="${KANBOARD_SMTP_HOSTNAME}"
MAIL_SMTP_PORT="${KANBOARD_SMTP_PORT}"
MAIL_SMTP_USERNAME="${KANBOARD_SMTP_USERNAME}"
MAIL_SMTP_PASSWORD="${KANBOARD_SMTP_PASSWORD}"
MAIL_SMTP_ENCRYPTION="${KANBOARD_SMTP_ENCRYPTION}"
MAIL_CONFIGURATION="false"
MAIL_FROM="${KANBOARD_MAIL_FROM}"

1. Provide valid mail settings via env vars
2. Run with docker-compose up
3. Login with admin:admin
4. Set admin email address
5. Restore email address
6. Email will arrive with wrong restoration address.
   In my case it will look like this

@vitoyucepi did you set the correct url (with ports) in Settings > Application Settings > Application URL?

[vitoyucepi]

@rafacamargo123 No, I didn't. Thank you for pointing out the setting.
https://docs.kanboard.org/en/latest/user_guide/settings.html?highlight=URL#application-url

Maybe application settings should be added to Admin guide and config file?
Should I open a new issue for that or I have to go to forum and post a feature request?

I've checked the settings page and think there should be global config file settings for all of them. So I can configure them via env vars.
