Hi Ingo,
imap have timeout 30 min and server and client keep connection (if kmail in imap folder)
Kmail don't need send packets with NOOP - maybe that send packet before 30 min or
 check connection when talk to imap server (I don't know what is better)
If kmail send 3-4 packet every 15 sec in network with 100 users online that is 
400/15 packets in second (10mbit network have bandwith 833 packets) 
I see 15000 in kmacctimap.cpp, but I don't know what another work mIdleTimer.
If mIdleTimer is only for disconnect, that best time is 29 min.

I don't beleive that Outlook is smarter (he keep connection, but disconnect after 30 min)
