Hi @rhett
Here a working snippet with gmail. Note that previously you require to create an app password in gmail:
EMAIL_DEFAULT_FROM=your_address@gmail.com
EMAIL_TRANSPORT_DEFAULT_HOST=smtp.gmail.com
EMAIL_TRANSPORT_DEFAULT_PORT=587
EMAIL_TRANSPORT_DEFAULT_USERNAME=your_address@gmail.com
EMAIL_TRANSPORT_DEFAULT_PASSWORD=your_app_password
EMAIL_TRANSPORT_DEFAULT_TLS=true
Those are the only email env variables you need to customize to make passbolt send emails with gmail.
Here some snip of the su -c 'bin/cake passbolt send_test_email' -s /bin/bash www-data
If you receive this email, it means that your passbolt smtp configuration is working fine.

Hope this helps
