Add the Mailhog service to Your .lando.yml File

First, add the following configuration to your .lando.yml file to set up the Mailhog service.

services:
  mail:
    type: mailhog
    hogfrom:
      - appserver
proxy:
  mail:
    - mail.lndo.site

Modify your settings.local.php

Next, update your settings.local.php file to configure the mailer sendmail command.

$settings['mailer_sendmail_commands'] = [
  ini_get('sendmail_path') . ' -t',
];

Configure the Symfony Mailer Module

Finally, add a new transport method for the Symfony Mailer module configuration. Navigate to /admin/config/system/mailer/transport and add a new Sendmail Tranport type.

Make sure to select the command you entered in settings.local.php

With these configurations, you'll have Mailhog set up and ready to capture outgoing emails, making your development process more efficient and debugging email-related issues much easier.
