How can I make a docker-compose file with mailhog and wordpress images work?

I have a docker-compose.yml file like this (you might have to go through the article in the link in it):

version: '3.3'

# + https://phauer.com/2017/test-mail-server-php-docker-container/

services:
  mailhog:
    container_name: mailhog_1
    image: mailhog/mailhog:v1.0.0
    ports:
      - "1025:1025"
      - "8025:8025"

  db:
    container_name: db_1
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
    restart: always
    environment:
      MYSQL_DATABASE: '...'
      MYSQL_USER: 'wordpress'
      MYSQL_PASSWORD: '...'
      MYSQL_ROOT_PASSWORD: 1111

  phpmyadmin:
    container_name: phpmyadmin_1
    depends_on:
      - db
    restart: always
    ports:
      - "8080:80"
    image: phpmyadmin/phpmyadmin
    environment:
      PMA_HOST: db:3306
      PMA_USER: root
      PMA_PORT: 3306
      PMA_PASSWORD: 1111

  wordpress:
    container_name: wordpress_1
    depends_on:
      - db
    image: wordpress:latest
    ports:
      - "80:80"
    volumes:
      - type: bind
        source: ./html
        target: /var/www/html
        volume:
          nocopy: true
    restart: always
    environment:
      WORDPRESS_DB_NAME: '...'
      WORDPRESS_DB_USER: 'wordpress'
      WORDPRESS_DB_PASSWORD: '...'
      WORDPRESS_DB_HOST: db:3306 # in Duplicator
      WORDPRESS_TABLE_PREFIX: 'wp_'
      WORDPRESS_AUTH_KEY: 'pune fraza unică aici ...'
      WORDPRESS_SECURE_AUTH_KEY: 'pune fraza unică aici ...'
      WORDPRESS_LOGGED_IN_KEY: 'pune fraza unică aici ...'
      WORDPRESS_NONCE_KEY: 'pune fraza unică aici ...'
      WORDPRESS_AUTH_SALT: 'pune fraza unică aici ...'
      WORDPRESS_SECURE_AUTH_SALT: 'pune fraza unică aici ...'
      WORDPRESS_LOGGED_IN_SALT: 'pune fraza unică aici ...'
      WORDPRESS_NONCE_SALT: 'pune fraza unică aici ...'
      PATH: /usr/local/go/bin:$PATH

volumes:
  db_data:

In the docker-compose up log I get besides all other stuff these lines (the first is the interesting one for me):

wordpress_1   | sh: 1: -t: not found
wordpress_1   | 172.19.0.1 - - [10/Mar/2020:16:43:40 +0000] "POST /wp-json/contact-form-7/v1/contact-forms/9/feedback HTTP/1.1" 200 926 "http://localhost/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36"
mailhog_1     | [APIv1] KEEPALIVE /api/v1/events

I do not know why the email command does not work (on my front-end I use the Contact Form 7 plugin for WordPress). On the front end the click on the Submit button results in an error shown with red:

A apărut o eroare la încercarea de a trimite mesajul. Te rog să încerci din nou mai târziu.

which means

There is an error when attempting to send the message. Please try again later.

It is the second message in the Messages tab in the contact form page. I did not change any of the messages there.

Can anyone tell me what is the cause of the sh: 1: -t: not found message from the wordpress_1 container?

Thank you.

sh: 1: -t: not found is caused by wp_mail() function failing to find /usr/sbin/sendmail in the WordPress container.

To make your docker-compose setup work you'll need to build a custom WordPress image (possibly based upon the official image) which would include some sort of /usr/sbin/sendmail emulation or implementation.
