Hello, I’m trying to enable WordPress SMTP mailing for Contact Form and Appointment plugins. My WordPress is running in a Docker container. My SMTP server needs to act like a mail relay.
I’m pretty sure I need a SMTP docker image with port configuration, but I’m not sure which image I need, and how to incorporate it in my docker-compose.
Here’s my docker-compose file
version: '3' services: # Database db: image: mysql:5.7 volumes: - db_data:/var/lib/mysql restart: always environment: MYSQL_ROOT_PASSWORD: ******* MYSQL_DATABASE: ******* MYSQL_USER: ******* MYSQL_PASSWORD: ******* networks: - wpsite # phpmyadmin phpmyadmin: depends_on: - db image: phpmyadmin/phpmyadmin restart: always ports: - '8080:80' environment: PMA_HOST: db MYSQL_ROOT_PASSWORD: ******* networks: - wpsite # Wordpress wordpress: depends_on: - db image: wordpress:latest ports: - '8000:80' restart: always volumes: ['./:/var/www/html'] environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_USER: ******* WORDPRESS_DB_PASSWORD: ******* networks: - wpsite networks: wpsite: volumes: db_data:
Right now WP Mail SMTP returns this error:
An issue was detected. This means your test email was unable to be sent. Typically this error is returned for one of the following reasons: - Plugin settings are incorrect (wrong SMTP settings, invalid Mailer configuration, etc). - Your web server is blocking the connection. - Your host is rejecting the connection.
