Hi,
To allow to send emails from @whitebox.aero emails, I have ordered a SMTP service for Whitebox - see
https://gitlab.com/whitebox-aero/whitebox/-/wikis/SMTP
-- don't hesitate if you run into any issue.
I will send you the password by email, privately.
Note that you can also use it for all outgoing emails from our servers, whenever you need to configure one. It will accept to send from any email @whitebox.aero - just let me know what you use.
