Expunge Deleted Messages from a Mailbox

Demonstrates the Chilkat Imap.Expunge method, which permanently removes all messages marked with the \Deleted flag from the currently selected mailbox. The mailbox remains selected. This example marks a message deleted with SetFlag and then expunges.

Background: IMAP deletion is two-phase, much like POP3. First a message is marked with the \Deleted flag (it still exists, just tagged); then EXPUNGE permanently removes every flagged message and renumbers the rest. Splitting the two steps lets a client mark several messages and remove them together, or unmark (undelete) before committing. Expunge keeps the mailbox selected; ExpungeAndClose does the same and then closes it.
