Hi all, I have installed openproject on my linux server using docker compose, following the instructions on https://docs.openproject.org/development/development-environment-docker/ and all the containers and running and working. However, I am having trouble with outbound emails. I have set up the email SMTP settings in the openproject web portal and it connects fine and when I sent a test email, it works. However, when I subsequently send email invitations nothing is sent, even though the interface reports back that the email was sent successfully. I have googled the issue and it seems a lot of people have experienced the same problem, however none of the answers I have found seemed to rectify this issue. Please could I get some help with this as I am not sure if there is something I'm missing.
