Steps for creating mail on the JES spool data set for CSSMTP

This topic provides the minimum information that you need to create mail that can be processed and forwarded by CSSMTP.

Perform the following steps to create mail on the JES spool data set for CSSMTP:

1. Set up JES so that CSSMTP can create, read, write, and purge data from the JES spool data set. See Steps for initial setup for CSSMTP.
2. Set up the mail to conform to the standardized syntax for text messages that are sent across networks. Mail messages have an envelope and contents. Envelopes contain all necessary information to accomplish transmission and delivery of the mail message content. The fields in the envelope are in a standard format.
3. Configure code page support.
   • Configure the code page of the input spool files with the TRANSLATE statement. The spool file must be written by using a code page that is supported by z/OS® Unicode Services. The default TRANSLATE code page is IBM®-1047.
   • Configure the code page used by the mail servers with the Charset parameter defined on the TargetServer statements. The default Charset code page is ISO8859-1.
   The spool file that contains the mail commands and body is recognized and translated by the Language Environment® iconv function to the following code pages:
   • The mail commands and headers are translated to EBCDIC (IBM-1047) for inspection by CSSMTP and then to the Charset code page before sending to the target server.
   • The mail body is translated to the Charset code page before sending to the target server.

   For information about Unicode Services, see z/OS Unicode Services User's Guide and Reference. For information about configuring the code page by using the Translate statement and the Charset parameter on the TargetServer statement, see z/OS Communications Server: IP Configuration Reference.

   
4. Set up the mail in one of the following formats:
   • A flat file generated using the sendmail bridge command that writes to the SYSOUT data set

     For information about using the sendmail bridge command, see Sendmail to CSSMTP bridge in z/OS Communications Server: IP User's Guide and Commands.

     
   • A flat file generated using the IEBGENER utility or batch jobs that write to the SYSOUT data set

     For information about using the IEBGENER utility to copy a mail file to a JES SYSOUT data set, see z/OS Communications Server: IP User's Guide and Commands.

   • Netdata generated from SMTPNOTE or from TSO xmit

     For information about using the SMTPNOTE command to compose a single mail message to one or more recipients and about using the TSO TRANSMIT (XMIT) command to send a mail file, see z/OS Communications Server: IP User's Guide and Commands.

   You must copy and customize the SMTPNOTE CLIST on every system where users can send mail with the SMTPNOTE command. For more information, see Steps for customizing the SMTPNOTE CLIST (optional).
