I have doubts that either of those IMAP servers would close the connection
out from underneath a client, without the client issuing a logout, closing
the TCP connection, or with the server hitting a 30 minute timeout.
More than likely, something else is happening that is unrelated to IDLE,
like a bug in the client (not sending a logout) or in the server, or with a
firewall complicating things.
How are you determining that the connections are staying open. Do you see
them in netstat?
Can you set up telemetry logging, or do a pcap trace to see what's going
