Mailu: Reverse proxy documentation does not support Traefik v2.x

[patryk-tech]

Hey! Thanks for this project, I am currently trying to deploy it on a server. While doing so, I have noticed that the configuration instructions for Traefik only provide the configuration for Traefik <= v1.7, as they use [[acme.domains]].

In Traefik v2+, SANs should be defined under routers, in the dynamic configuration, or under entrypoints, in the static config.

Examples from the traefik docs below...

Dynamic configuration examples using routers

TOML

## Dynamic configuration
[http.routers]
  [http.routers.routerbar]
    rule = "Host(`snitest.com`) && Path(`/bar`)"
    [http.routers.routerbar.tls]
      certResolver = "bar"
      [[http.routers.routerbar.tls.domains]]
        main = "snitest.com"
        sans = ["*.snitest.com"]

YAML

## Dynamic configuration
http:
  routers:
    routerbar:
      rule: "Host(`snitest.com`) && Path(`/bar`)"
      tls:
        certResolver: "bar"
        domains:
          - main: "snitest.com"
            sans:
              - "*.snitest.com"

Docker Labels

  - "traefik.http.routers.router1.tls.domains[0].main=foobar"
  - "traefik.http.routers.router1.tls.domains[0].sans=foobar, foobar"
  - "traefik.http.routers.router1.tls.domains[1].main=foobar"
  - "traefik.http.routers.router1.tls.domains[1].sans=foobar, foobar"

Static configuration using entrypoints

TOML file

[entryPoints]
  [entryPoints.EntryPoint0]
    address = "foobar"
    [entryPoints.EntryPoint0.http]
      [entryPoints.EntryPoint0.http.tls]
        [[entryPoints.EntryPoint0.http.tls.domains]]
          main = "foobar"
          sans = ["foobar", "foobar"]

YAML file

entryPoints:
  EntryPoint0:
    address: foobar
    http:
      tls:
        domains:
        - main: foobar
          sans:
          - foobar
          - foobar

Hi There,

The Mailu-Project is currently in a bit of a bind! We are short on man-power, and we need to judge if it is possible for us to put in some work on this issue.

To help with that, we are currently trying to find out which issues are actively keeping users from using Mailu, which issues have someone who want to work on them — and which issues may be less important. These a less important ones could be discarded for the time being, until the project is in a more stable and regular state once again.

In order for us to better assess this, it would be helpful if you could put a reaction on this post (use the :smiley: icon to the top-right).

• 👍️ if you need this to be able to use Mailu. Ideally, you’d also be able to test this on your installation, and provide feedback …
• 🎉 if you find it a nice bonus, but no deal-breaker
• 🚀 if you want to work on it yourself!
  We want to keep this voting open for 2 weeks from now, so please help out!

Hey!

Sure, Hacktoberfest guilted me into giving it a try.
