What makes you happy ?

I installed Little Snitch on the mini for amusement. It requires a restart. On that restart LS shows Mail.app wanting to make several outgoing connections.
I don’t use Mail, I’ve never used Mail, I’ve never run it, I would never run it. I have never given it permission to run, it’s not in my login items. So wtf is it doing running? Is this one of those ‘Apple knows best’ moments? I probably can’t install it - like so many other Apple apps it seems - but I’m certainly out now for a way to cripple it into submission - it will not connect.
