@ksis Do we need to change anything in https://github.com/goalgorilla/drupal_social/blob/master/docker-compose.yml#L34 or https://github.com/goalgorilla/open_social_scripts/blob/master/install/install_script.sh#L123 ?

Hi @navneet0693, no changes are needed in the docker-compose.yml, but it makes sense to remove everything related to the swiftmailer from the installation script. Also I will think about how to properly create mailer transport for symfony mailer so that it would work with mailhog.

@ksis I see some tests are still failing. For example test with tag @bulk-mails. I think we need to change it since there is no ability to test emails with Symfony Mailer.

Also, could you investigate if it will be possible to rebuild the ability to test emails in Symfony Mailer with the Spool method?
