Downloads email from an IMAP mailbox and deletes emails individually (one by one). Ruby

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# Connect to an IMAP server.
# Use TLS
imap.put_Ssl(true)
imap.put_Port(993)

# Select an IMAP mailbox

# To mark a complete set of emails for deletion, call SetFlags:
success = imap.SetFlags(messageSet,"Deleted",1)

# Messages can also be marked for deletion individually:

    # The email is not actually deleted until Expunge or
    # ExpungeAndClose is called.
