The HELO SMTP command is following the syntax as described in RFC 821. HELO <SP> <domain> <CRLF>
domain is a required parameter. For the z/OS SMTP server it can be any string. The string itself is ignored by the server. A possible use is to identify the z/OS LPAR that created the mail message. Since this is a CICS task creating the mail message, the CICS SOCKET API could be used to obtain the host name. Use the gethostname() function. Use the socket() function to obtain a socket, call the gethostname() function and call the close() function to close the socket. Or use the SMFID, the system name from the CVTSNAME field, or the CICS system name. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
