Sensitivity checking
The,  ,  , and   channel options set an upper limit on the sensitivity of messages that may be accepted by a destination channel. The default is ; i.e., messages of any sensitivity are allowed through. A message with no Sensitivity: header is considered to be of normal, i.e., lowest, sensitivity. Messages with a higher sensitivity than that specified by such a channel option will be rejected when enqueued to the channel with an error: message too sensitive for one or more paths used Note that the MTA does this sort of sensitivity checking at a per-message, not per-recipient, level: if a destination channel for one recipient fails the sensitivity check, then the message bounces for all recipients, not just for those recipients associated with the sensitive channel. (Also note that the   channel option, if used, postpones the timing of the message rejection.)

The   MTA option permits logging of the sensitivity of messages passing through the MTA.
