Lines to return MTA option

Notification message MTA options:  (integer)
The  MTA option controls how many lines of message content the MTA includes when generating a notification message for which it is appropriate to return only a sample of the contents. The default is 20. Note that this option is irrelevant when generating a NOTARY bounce message, where either the full content or merely headers are included, according to the choice specified during the initial submission of the message. So in practice, this option is mostly only relevant to the warning messages the MTA&#x27;s   sends about messages awaiting further delivery retries in the MTA&#x27;s message  queue area.

Note that setting =0 will cause the warning messages generated by the MTA regarding not-yet-delivered messages to contain only message headers (none of the body of the original message).
