Troubleshooting
Problem
Whenever the SMTPNOTE command is used to send a mail message from a TSO ID (or batch job) to an Internet mail address, it fails with an EZA5579E message.
Symptom
EZA5579E UNABLE TO TRANSMIT DATA TO 'SMTP, ' AT 'YKTVS'Cause
As a part of installing the z/OS Communications Server component, you must customize the SMTPNOTE exec for the local environment. This error is a result of either missing that customization step or running with an unmodified version of SMTPNOTE.
Resolving The Problem
Refer to the IP Configuration Guide (SC31-8775), Step 3 of Configuring the SMTP Server for a description of the items that need to be customized in the SMTPNOTE exec . Copy the original version of the SMTPNOTE exec from the SEZAINST library shipped with the product to a library that is in the SYSPROC (or SYSEXEC) concatenation for all users.
The following shows the section in the SMTPNOTE exec that you need to update. The values for the hostname and smtpnode need to be modified on every customer system (and are the cause of the EZA5579E message). But you might want to change the other values as well to match the local environment. See the IP Configuration Guide and comments within the exec (shown here) which describe these values further.
/**** ****/
/**** The following lines set five variables which affect the ****/
