ZOSMIGV2R2_Next_CS_SMTPDMTA

Description:

Checks whether the SMTPD daemon is in use as a Mail Transfer Agent (MTA) on this system (SMTPD is listening on port 25). Support for the SMTPD daemon will be withdrawn in a future release of IBM® z/OS® Communications Server and MTA functionality will no longer be available on z/OS.

If this check determines that SMTPD is running as an MTA on this system (SMTPD listening on port 25), it will continue to be reported for the duration of this IPL, or as long as this Migration Health Check is active. When this exception condition is detected, message ISTM026E is issued and is followed by message ISTM900I which indicates the date and time that the SMTPD daemon was last detected acting as an MTA, even if it has since been removed from the system or usage of it as an MTA has stopped. Therefore, if this exception has been corrected (for example, SMTPD no longer listening on port 25 on the system) you can use message ISTM900I to determine whether a new use of the SMTPD daemon's MTA function has been detected, or whether the exception condition is related to the earlier detection of the SMTPD daemon's MTA function.

Reason for check:

Because SMTPD will no longer be supported on z/OS in future releases, and its MTA function will not be available on z/OS, IBM suggests that customers who are currently using or plan to use SMTPD as an MTA, migrate that function to other operating system platforms that continue to provide MTA support, such as Linux on z Systems.

z/OS releases the check applies to:

z/OS V2R2

User override of IBM values:

The following sample shows the defaults for customizable values for this check. Use this sample to make permanent check customizations in an HZSPRMxx parmlib member used at IBM Health Checker for z/OS startup. If you just want a one-time only update to the check defaults, omit the first line (ADDREPLACE POLICY) and use the UPDATE statement on a MODIFY hzsproc command. Note that using non-POLICY UPDATEs in HZSPRMxx can lead to unexpected results and is therefore not recommended. End of change
