Hey Zusammen,
ich habe mit diesem Codebeispel mal versucht eine Mail zu verschicken:

Leider kommt immer folgende Fehlermeldung vom Server zurück:
550 that smtp username's account is not allowed to send
Was bedeutet das?
Muss für SMTP2GO noch mehr einrichten, als nur einen Account?
Nach dem Video hier: https://www.youtube.com/watch?v=WBcnYa6CY9Y ist das ganz simpel beschrieben, aber so läuft es wohl leider nicht...oder nicht mehr.
Auf dem Dashboard von SMTP2GO sehe ich das hier:
Hat jemand ne Idee? Muss ich jetzt noch eine Domain registrieren oder gibt's auch eine andere Lösung Mails vom Arduino zu versenden?
