MTA_HDRMSG_FILE

Specify the name of an input file containing both the message header and message body. The content of the file represents an RFC 2822 formatted message with at least one blank line separating the RFC 2822 header from the message body. The mtaSend() routine uses the header lines from the input file to form an initial message header. This initial header is then modified as necessary.

The item_address and item_length fields specify the address and length of a text string containing the input file’s name. The length of the string may not exceed ALFA_SIZE bytes.
