Enterprise Manager: E-Mail reports and error adding device

Hi, i'm installing EM 3.1.1 HF4 and i have one problem and one question:

• Trying to add a specific device i have the following error: iControl error: 'Unexpected exception type. Message: icontrol did not return the same number of certificate bundles for bundle filenames'. Other devices can be added without problem.

   

• In order to enable e-mail alerts, i made two tests:

   

  • Only with the administration IP set (with the respective gateway), e-mail not sent
  • Added a Self IP with all the respective settings, e-mail sent.

  It is possible only work with the administration IP?
