Issue/Introduction

When the Symantec Endpoint Protection 12.1 (SEP) feature Internet Email Auto-Protect is installed on the same computer as the Symantec Endpoint Protection Manager (SEPM), it can sometimes prevent the SEPM from sending email.
 

This issue only occurs on desktop class operating systems, such as Windows Vista, Windows 7, Windows 8, or Windows 8.1.

If SEPM mail debugging is enabled (see TECH102413 for steps), the following error can be seen in %temp%\scm-ui-*.err after a failed test email:

com.sygate.scm.util.mail.EmailException: javax.mail.MessagingException: Could not connect to SMTP host: 192.168.1.11, port: 25;  nested exception is:  java.net.SocketException: Network is unreachable: connect

Also reported in ...Manager\tomcat\logs\catalina.err, SecurityAlertNotifyTask-0.log (Notification emails), or ScheduledReportingTask-0.log (Scheduled reports).

Resolution

This problem is fixed in Symantec Endpoint Protection 12.1 Release Update 5 (SEP 12.1.5). For information on how to obtain the latest build of Symantec Endpoint Protection, read Obtaining the latest version of Symantec Endpoint Protection or Symantec Network Access Control.
