I’m going to continue the discussion started in [this thread](https://forum.mautic.org/t/a-small-guide-to-send-mails-using-doctrine-for-queue-in-mautic-5/33118/4) here since it is more about Docker stuff than the guide developed by @rcarabelli .

My latest discovery is that, from the three docker containers I have (web, worker and cron), the only one that actually interacts with Gmail (a.k.a. does send emails) is web. The other two will simply silently eat the messages but fail to do anything useful with them.

I fail to see the difference between them. The env variables are the same, the config file (`local.php`) is too…
