On my Ubuntu + [Nginx + PHP-FPM + MySQL + Exim + Courier] server, I have only one email address and a bunch of forwarding aliases. Everything is working.
But when I use
htop, I see multiple processes for that single email address. For example: 4 imapd, 4 couriertls, 6 courier authdaemond, 4 couriertls, etc.
Is it normal?
