Drupal 10 - Symfony Mailer + Mailhog on Docksal - Local settings snippet

settings.local.php

<?php

# If you have a SMTP setup, such as for example 'Postmark', where we have a config file `symfony_mailer.mailer_transport.postmark.yml`,
# this override would locally in Docksal make the Mailhog handler for what in prod is Postmark:

$config['symfony_mailer.mailer_transport.postmark']['configuration']['user'] = '';
$config['symfony_mailer.mailer_transport.postmark']['configuration']['pass'] = '';
$config['symfony_mailer.mailer_transport.postmark']['configuration']['host'] = 'mail';
$config['symfony_mailer.mailer_transport.postmark']['configuration']['port'] = '1025';
