List IMAP Mailboxes

Demonstrates the Chilkat Imap.MbxList method, which lists matching mailboxes and appends them to a Mailboxes object. The first argument selects subscribed-only, the second is a reference name, the third is the mailbox name pattern, and the fourth is the Mailboxes object. This example lists all mailboxes and prints each name. (The object is not cleared on success, so avoid reusing one across calls to prevent duplicates.)

Background: This corresponds to the IMAP LIST command (or LSUB when subscribed-only is requested). The pattern uses IMAP wildcards: * matches across hierarchy levels while % matches within a single level, so Archive/% lists just the direct children of Archive. Each returned mailbox also carries flags you can inspect — for example HasInferiors (has sub-folders) and IsSelectable — which is how a client renders a folder tree.
