ZOSMIGV2R2_Next_CS_SENDMAILMSA

Description:

Checks whether sendmail is being used as a Mail Submission Agent (MSA) on this system (sendmail is listening on port 587). Support sendmail will be withdrawn in a future release of IBM® z/OS® Communications Server and the MSA function will no longer be available on z/OS.

If this check determines that sendmail is acting as an MSA on this system, 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 ISTM022E is issued and is followed by message ISTM900I which indicates the date and time that the sendmail MSA was last detected, even if it has since been removed from the system or usage of it has stopped. Therefore, if this exception has been corrected (for example, sendmail MSA function no longer being used on the system) you can use message ISTM900I to determine whether a new use of the sendmail MSA function has been detected, or whether the exception condition is related to the earlier detection of the sendmail MSA function.

Reason for check:

Because sendmail will no longer be supported on z/OS in future releases and the MSA function will no longer be available on z/OS, IBM suggests that customers who currently use or plan to use sendmail as a mail submission agent (MSA), migrate that function to a compatible third-party solution or to other operating system platforms that continue to support MSA functions, 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
