Which version of the application are you using?:
Please choose how you got the application: Installer (Windows, Linux, macOS), cloud image (AWS, GCE, Azure, ...) or VM (VMDK, VBOX):
Google Cloud Engine via Bitnami Cloud Launcher
Have you installed any plugin or modified any configuration file?:
No except sample-data
Describe here your question/suggestion/issue (expected and actual results):
I try your Magento Stack on a Google Cloud VM and it seems you included a module for STMP sending mail (with gmail account or Google app)
Could you tell me which one you add cause this is not included in a fresh Magento install via Composer.
Thanks for your help.
