Permit to manage mail differently

Hello,

In order to be able to send emails using my current SMTP server, I need to have more configuration options. Current support of ssmtp is really basic in this role. So I will use another mail client.

I propose to be able to disable management of mails on server by ssmtp. This change is backward compatible with current installations.

Thank you @nqb, could you please just add a line in README file about this new variable ?

Also, is it on purpose that you used double underscore in variable name ? (none of my variables use double underscore so far, so feel free to change to simple underscore if not done on purpose, otherwise I will accept it with double underscore)

Hello @remi-filament,

No problem for line in README.

Double underscore is on purpose.

When I develop roles, I try to prefix all variables with role name. The double underscore is a best practice coming from DebOps project which help you distinguish role name if you used dependent variables.

Fine we can keep your naming convention
