The customer sends a CALL-object with a registered output as attachment. He did this already in V9 (Server and Agent) and it worked. After upgrade of Server and Agent to V11.2 it does not work anymore. If he uses Server V11.2 and Agent V9 it works.
Comparing behavior the V9 and V11.2 Agent, following can be seen:
Both agents run on the same machine in the same client. Even the binaries are in the same directories with different ini-files. I.e., they use the same uc_client_settings and the comparison shows, the ini-files are equivalent. Comparing traces, you see:
<Please see attached file for image>
In the comparison you see that SNDMAIL in V9 and SNDMAIL2 in V11.2 both use the same SMTP-server (smtpintern.frankfur). In the green part however, V9 goes to SLG8FRM4.corp.standardlife.com
(the correct MS mail-server) while V11.2 uses fra-uc1.frankfur. This is wrong as it is the AIX-machine the Agents and the AE run on. Ie.e, the Agent connects to the AIX's built in mail server, what is wrong.
