With an IMAP client [in the early days the "I" stood for
"interactive"] you will have one active connection to the server for
each login and an additional one for each open mail "folder" under a
login. So generally that means a minimum of two active connections,
often rather more. As such, you can't go "dark" from the perspective
of the IMAP server unless you use "offline mode" or otherwise log out.
