Ports config in docker-compose.yml and admin ui url

[gvnt]

Hi,
I think i found a small bug with your admin ui.
When i try to use this port set up (because i will need my port 80)

front:
image: mailu/nginx:$VERSION
restart: always
env_file: .env
ports:
- "$BIND_ADDRESS4:11223:80"
- "$BIND_ADDRESS4:11224:443"
- "$BIND_ADDRESS4:110:110" ...

The web mail seems work perfectly, but not all pages of admin ui.
The port is not pass in somes urls.

For example
:11224/admin -> not working, redirect to /admin/ui
:11224/admin/iu -> not working, redirect to /login?next=ui.index
:11224/login?next=ui.index -> working well

After somes searchs, i found this pallets/flask#824
Maybe a problem with "url_for" in Mailu/core/admin/mailu/init.py ?

This is interesting as I did run the admin interface on a custom port once without facing the issue. Thank you for reporting, I will look into it.
