Are you sure disabling IDLE helps with that? AFAIK most clients
keep persistent connections to server regardless of their ability
to IDLE.

No expert here but netstat shows persistent established connections
for users with blackberrys.

Ah, ok. I think blackberry is an exception here. But actually you can
disable IDLE by changing imap_capability setting manually. Set it to
the default CAPABILITY reply you get from Dovecot, just remove IDLE.
