Ils ont raison, je ne veux pas de modèle à l'américaine et vais donc mettre à exécution ce que je me suis dit depuis le #cashinvestigations sur les données personnelles (https://www.youtube.com/watch?v=cb3jfxMnZU4) : #boycott de toutes les pharmacies qui utilisent et diffusent aux patients des adresses #gmail !

You have put your finger on the problem, I believe.
So, am I reading this right?
It seems to be claiming:
Since the "ISP" through whom I am attempting to send mail is #DigitalOcean, I find item #1 to be dubious. They are not blocking my outgoing mail port, and I have no problems sending to most recipients (Google and Microsoft being the only exceptions I'm aware of).
DigitalOcean seems to encouraging its users to use a 3rd-party service -- but I'm already paying them for hosting, and managing my own email service; I don't want to pay yet another service just for the privilege of being allowed to send messages to Gmail's increasingly walled garden.
Is it time to formally #boycottGmail?
