Carbon Black App Control (formerly Cb Protection)

Issue/Introduction

The following error is received then clicking test e-mail: "Test mail error: Unable to connect to the remote server"

Environment

  • App Control Server: All Supported Versions

Cause

This can potentially be caused by:
  • A problem with the network connectivity between the App Control server and the e-mail server
  • Third party antivirus interfering with the Reporter service
  • SMTP emails being caught as spam

Resolution

  • Confirm whether or not it's a network connectivity issue:
    • While logged in as the Carbon Black Service Account user, telnet to port 25 for unsecured configuration, or ports 465 and 587 for secure configurations.
  • Confirm the Server Exclusions in any antivirus/security products on the application server.
  • Confirm that no SMTP email security software is blocking the email.

Additional Information

If it is required add the SMTP email to an 'approved list'
