Good evening.
I have an installation running ISE version 2.6 patch 1 and 2 where smtp realying doesn't work and the guest logging seems to indicate that internal process might be the culprit.
The log messages contains lines like this:

The logging in the firewalls indicate that the email are passing freely and another ISE installation on the same subnet are not subject to these email failures. The email address i valid as well as the SMTP realy server entry.
What is this smtp.mail.sun.com comming from? There is not a configured line anywere in this installation unless contained in the code itself...
Anyone who can explain these log lines?
