Latest versions of mailhog and mongodb incompatible (docker-compose)

[ghost]

Replicate using this docker-compose.yml:

version: "3.9"
services:
  mailhog:
    image: "mailhog/mailhog:latest"
    ports:
    - "50001:8025"
    - "50002:1025"
    environment:
      MH_STORAGE: mongodb
      MH_MONGO_URI: "mongo:27017"
    depends_on:
    - mongo

  mongo:
    image: "mongo:latest"

I went back to Mongo 4.20 to make it work.
If you need a more recent Mongo, just add a second mail_mongo service with version 4.20 or so

See mailhog/storage#12
You can compile a working version with: https://github.com/vmary2014/MailHog

Thanks to comment #1697868253

I was able to build a new version with a working storage and also I had to fix sort order for mongodb to descending, that's why I'm using my own fork for storage.

Urls like mongodb://127.0.0.1:27017 now working!

Here is a dockerfile, maybe it will help someone
