Caller-Supplied Output Routine

To use a caller-supplied output routine (for example, decode_write()), supply the address of the output routine along with the MTA_DECODE_PROC item code to mtaDecodeMessage().

Each line passed to the output routine represents a complete line of the message to be output. The output routine must add to the line any line terminators required by the output destination (for example, carriage return, line feed pairs if transmitting over the SMTP protocol, line feed terminators if writing to a UNIX® text file, and so forth).
