MailHog settings

In case of MailHog, the file is compose/docker-compose.override.yml-mailhog. This file must be copied into the root of the Devilbox git directory.

What	How and where
Example compose file	compose/docker-compose.override.yml-all or compose/docker-compose.override.yml-mailhog
Container IP address	172.16.238.201
Container host name	mailhog
Container name	mailhog
Mount points	none
Exposed port	8025 (can be changed via .env)
Available at	http://localhost:8025
Further configuration	php.ini settings need to be applied per version

MailHog env variables

Additionally the following .env variables can be created for easy configuration:

Variable	Default value	Description
HOST_PORT_MAILHOG	8025	Controls the host port on which MailHog will be available at.
MAILHOG_SERVER	latest	Controls the MailHog version to use.

Instructions

1. Copy docker-compose.override.yml

Copy the MailHog Docker Compose overwrite file into the root of the Devilbox git directory. (It must be at the same level as the default docker-compose.yml file).

host> cp compose/docker-compose.override.yml-mailhog docker-compose.override.yml

* docker_compose_override_yml * add_your_own_docker_image * overwrite_existing_docker_image

2. Adjust PHP settings

The next step is to tell PHP that it should use a different mail forwarder.

Let's assume you are using PHP 7.2.

# Navigate to the PHP ini configuration directory of your chosen version
host> cd cfg/php-ini-7.2

# Create and open a new *.ini file
host> vi mailhog.ini

Add the following content to the newly created ini file:

[mail function]
sendmail_path = '/usr/local/bin/mhsendmail --smtp-addr="mailhog:1025"'

php_ini

3. Adjust .env settings (optional)

By Default MailHog is using the host port 8025, this can be adjusted in the .env file. Add HOST_PORT__MAILHOG to .env and customize its value.

Additionally also the MailHog version can be controlled via MAILHOG_SERVER.

HOST_PORT_MAILHOG=8025
MAILHOG_SERVER=latest

env_file

4. Start the Devilbox

The final step is to start the Devilbox with MailHog.

Let's assume you want to start php, httpd, bind and mailhog.

host> docker-compose up -d php httpd bind mailhog

start_the_devilbox

5. Start using it

• Once the Devilbox is running, visit http://localhost:8025 in your browser.
• Any email send by any of the Devilbox managed projects will then appear in MailHog

TL;DR

For the lazy readers, here are all commands required to get you started. Simply copy and paste the following block into your terminal from the root of your Devilbox git directory:

# Copy compose-override.yml into place
cp compose/docker-compose.override.yml-mailhog docker-compose.override.yml

# Create php.ini
echo "[mail function]" > cfg/php-ini-7.2/mailhog.ini
echo "sendmail_path = '/usr/local/bin/mhsendmail --smtp-addr=\"mailhog:1025\"'" >> cfg/php-ini-7.2/mailhog.ini

# Create .env variable
echo "HOST_PORT_MAILHOG=8025" >> .env
echo "MAILHOG_SERVER=latest" >> .env

# Start container
docker-compose up -d php httpd bind mailhog
