Steps for Importing SMTP Server's Custom SSL Certificate into 11g / 12c OMS for Sending Email Notifications Using SSL / TLS (Doc ID 1543095.1)

Last updated on OCTOBER 24, 2013

Applies to:

Enterprise Manager Base Platform - Version 11.1.0.1 to 12.1.0.3.0 [Release 11.1 to 12.1]
Information in this document applies to any platform.

Goal

Trying to configure the Email notification method in the 11g / 12c Enterprise Manager Console UI.

-  In the Setup -> Notifications -> Notification Methods page, SSL option has been chosen in the 'Use Secure Connection'.
   When the 'Test Mail Servers' button is clicked, it returns the error:

 <smtp.domain>:<port> Test failed with message: "Exception reading response" [SMTP Server:  <smtp.domain>:<port>, User name: <username>, Secure Connection: SSL]

Or

-  In the Setup -> Notifications -> Notification Methods page, 'TLS (if available)' option has been chosen in the 'Use Secure Connection'.
   When the 'Test Mail Servers' button is clicked, it returns the error:  

<smtp.domain>:<port> Test failed with message: "Can't send command to SMTP host" [SMTP Server:  <smtp.domain>:<port>, User name: <username>, Secure Connection: TLS]

-  From the OMS machine, it is possible to resolve the hostname / IP address of the SMTP server and there is no firewall in between.

-  Verifying the SMTP server logs indicate that the OMS has been able to reach the SMTP server but once the SMTP server sends its SSL certificate, there is no further communication from the OMS.

This occurs as the SMTP server specified has been configured with a custom SSL certificate which needs to be imported into the Enterprise Manager. This document provides the steps for importing the SMTP server's custom SSL certificate into the JDK used by the OMS, for sending Email notifications.
