Since: Dev Builds Only
The functionality described in this section requires a dev build of KumoMTA. You can obtain a dev build by following the instructions in the Installation section.
Cancels any xfer routing that might be applied to msg (which must be a
Message object).
If the message is not configured to xfer then this function will not make any changes to the message.
If opt_reason is specified, it will be used as the reason string in an
AdminRebind log record to capture any queue change that might occur due to
calling this function.
If opt_reason is not specified (omitted, or is explicitly set to nil),
then no AdminRebind log entry will be produced.
