Customizing the sendmail bridge

When the email protocol is selected in a printer definition, IP PrintWay uses a sendmail to z/OS® Communications Server SMTP (CSSMTP) bridge as the mail transport to send emails to the recipients listed in the printer definition.

If you did not already customize the sendmail bridge, you must do so before IP PrintWay can send output to email destinations. For information about how to customize the sendmail bridge, see z/OS Communications Server: IP Configuration Guide.

Guidelines: Follow these guidelines when you customize the sendmail bridge:
  1. The sendmail bridge depends on the domain name server (DNS). Therefore, be sure to set up this component correctly.
  2. An alias name is a file that is defined to the sendmail bridge and lists one or more actual email addresses. The sendmail bridge expands alias names into email addresses when it sends an email. In z/OS V2R3, only existing alias files are supported. You cannot create new alias files to be used with the sendmail bridge.
  3. Configure the z/OS system so that a firewall does not prevent users from sending emails. You can receive replies from the email unless you are a TSO or z/OS UNIX System Services user. To receive replies from the email, specify the reply email address in the reply-to field of an email header or in the mail-reply-address job attribute. If none is specified, the Reply address in the printer definition is used.
  4. If you do not install the sendmail bridge in the default directory, /bin, specify the full path name of the the sendmail bridge in one of these ways:
    • If you run IP PrintWay extended mode and dynamic configuration is enabled, specify the mailer-path-name attribute in the system configuration definition.
    • If you run IP PrintWay extended mode and dynamic configuration is not enabled, specify the AOPMAILER environment variable in the aopstart EXEC.
    • If you run IP PrintWay basic mode, specify the AOPMAILER environment variable in the IP PrintWay startup procedure.
  5. If you need to specify sendmail options, specify the options in one of these ways:
    • If you run IP PrintWay extended mode and dynamic configuration is enabled, specify the mailer-options attribute in the system configuration definition.
    • If you run IP PrintWay extended mode and dynamic configuration is not enabled, specify the AOPMAILER_OPTIONS environment variable in the aopstart EXEC.
    • If you run IP PrintWay basic mode, specify the AOPMAILER_OPTIONS environment variable in the IP PrintWay startup procedure.
    IP PrintWay specifies the options that you specify in addition to the -i option when it sends emails; however, only a limited number of options are supported by the sendmail bridge in z/OS V2R3.
