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
torF5while runninghtop. I’m pretty sure they shouldn’t increase if you add more email addresses.
