MailMan will then notify you that the message has been sent.
You can use the Transmit Now action code (i.e., 'T') to have MailMan
send your message to all recipients. You would use this action code after

To send a message now, enter a 'T' or press the Return/Enter key to accept
the 'Transmit now' default at the 'Select Message option: Transmit now//'
