If the message is returned, NTMail can be instructed to either suspend or remove the address form the list. These messages may optionally be sent to the BadMes directory for future analysis or deleted. Messages from NTList's list manager or NTMail's mail manager are not allowed to be posted to a list. Any such messages may optionally be sent to the BadMes directory for future analysis. Messages that have been posted back to a list for a second time are rejected and posted back to the person who caused the error.
Removes return receipt requests.
Several email clients use priority header clauses to request receipts are returned when the mail is read. These are removed before a message is posted to a list. Messages from a NULL account are not processed. Most messages from NULL accounts are from auto responders and, as such, should not be propagated to list members. Messages sent to the list with one of the words 'subscribe', 'unsubscribe', 'digest', 'leave', 'join', 'help', 'dir', 'get', 'put', cause NTList to return the list's help message to the sender.
