Yes, sorry, from Mail on an iPhone 5S.

Watching the logs, it makes many connections to the IMAP server (one per 
mailbox?), so yes, it is definitely using the server.  Eventually it 
runs into the connection limit, closes all the connections then tries to 
open them all again.  You can see the entire process takes about a 
minute.

I guess the next step is to figure out IMAP logging, but I was wondering 
if anyone else had had success with getting Dovecot to perform well in 
this scenario.  From the response thus far it seems like the answer may 
be no.
