Hi,
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 top or 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?

Yes, these processes that you’re seeing are most likely threads. You can see it more clearly by pressing t or F5 while running htop. I’m pretty sure they shouldn’t increase if you add more email addresses.
