Hello,
Who is affected: people that did a fresh install of 3.8. Are not affected: people using docker or that upgraded from 3.7 or earlier.
What is happening: The emails are not sent when the SMTP configuration is stored in DB and there is no Email key config in passbolt.php (as it should for new installs). Test email works.
Why is it happening: The reason is that the “From” address is not set correctly with the new config coming from DB. So the SMTP server will reject the emails because the from adress is not correct (as passbolt fallbacks on the default from email from app.php).
When will it be fixed: We’re working on a fix that will be released with the 3.8.1 tomorrow. A workaround in the meantime is to set the from email address in config/app.php.
Sorry for the inconvenience and thank you for your patience.
