Hi Alexey,

Maybe I misunderstood what Arnt said.
It should be mailboxes whose events the client wants to get.

1、As the following paragraph (beginning with "/////////") said, the client 
sends large numbers of STATUS commands for mailboxes immediately after 
starting NOTIFY and the server sends large numbers of STATUS responses for 
these mailboxes.
2、What I said meant that the server sends the unsolicited STATUS responses 
for these mailboxes directly without receiving the large numbers of STATUS 
commands.

//////////////////////////
The NOTIFY command handles that nicely, just one wildcard and hardly any 
responses, but the client also has to send 1000 STATUS commands immediately 
after starting NOTIFY, so for a two-hour IMAP connection that's 1001 
commands and 2006 responses in order to notify the client of 4 events.
