Check the Last Known IMAP Connection State

Demonstrates the Chilkat Imap.IsConnected method, which returns the last known connection state without sending any data to the IMAP server. A true result does not prove that an idle connection is still usable. This example connects and reads the state.

Background: IsConnected is a cheap, cached check — it reports what Chilkat last observed without touching the network. That makes it fast, but it can be stale: a server or firewall may have silently dropped an idle connection. When you need to be sure the connection is actually alive, send a lightweight round trip such as Noop, or use CheckConnection for a low-level socket probe.
