Hi everyone,
I have installed Passbolt CE using Docker Rootless.
Everything seems to be working regarding the SMTP configuration:
-
The test emails are sent successfully.
-
Notification emails (e.g., when a folder is shared) are also working fine.
However, users do not receive “invitation” emails. I don’t see any errors in the GUI, the logs, or the database. It seems like the invitation emails are stuck in the queue. But they are processed because I see the status changed.
Thanks for your help!
