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

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.
