how? do you not have a seperate configuration for you production
environment?

if would you like to send emails from your production environment, then
why don't you employ the "classes and inheritance" pattern, suggested
here:
https://flask.palletsprojects.com/en/2.0.x/config/#development-production

or you override SERVER_NAME from the environment:
https://flask.palletsprojects.com/en/2.0.x/config/#SERVER_NAME

employ dotenv to make that transparent and easy for yourself.

or introduce an option to the cli command, like --server-name to set it
on a per command basis explicitly.

there might well be more ways and of course, what's best, depends on
your usecase.


best,

ub
