Yes, except I had been finding there were times (e.g. the first 5 tests 
I did today which didn't notify, and the one where it did notify, but 
only after 6 minutes)

Since I have poll disabled on inbox, I know that if I get notified, it 
is from push.

K9 default IDLE is 24 minutes but can be altered (settings, account, 
fetching, advanced)

I really don't want notifications for spam thanks.

You can probably use a combination of push on 1st class folders and 
polling on 2nd class folders, I don't but it's a potentially useful 
concept.

15 mins.

Dunno, not been into settings for a while.
