WordPres isn't Working

WordPres isn’t Working With Email Sender With reverse proxy and https in Docker

 

You need to either run a container with a smtp server and map that to your wordpress container or you need to map the HOST server smtp to your wordpress container

You can do that by running

docker run --extra_host "mail:<hostprivateip>" ... wordpress

Or you should use docker-compose for the same

version: '3'
services:
  app:
    image: wordpress
    ...
  mail:
    image: <somesmtpimage>
