Install mails after initial setup

Hi,

I have installed my server without mails services (except exim), as my client say “no I don’t need to host any mails on the server”…
But ofc, once everything is up, “oh finally I have forget that I have to host some mails”…

I have find some topic on the forum, and it seem that the easiest way is just to reinstall everything…

This is always the case ? Except manually going through the install script to get all the custom setup, there is no “easy” way to do that ?

atm the server is not in production, and I can reinstall everything if needed…

No sadly no …

Thx, I just wanted to be sure !
