Setting up a mail-server is no fun. Definitively not trivial. Certainly nothing to be done in 10 minutes.
@Freedombox: since when is promoting free software projects wrong on this list? Congratulation to you being free without FreedomBox. Maybe you can go even a step further and do it without free software! (Rumor has it you can write all code just by yourself - with 10 minutes at hand and the right tutorials) in case i just fed a troll - bon apetit.
