This is the default option. 1 message is sent by email to the address in the destination parameter. This is the only message type where the fourth parameter, extra_headers is used. 2 No longer an option. 3 message is appended to the file destination. A newline is not automatically added to the end of the message string. 4 message is sent directly to the SAPI logging handler.
