Whitelisting in Libraesva

This guide walks you through the steps to ensure system emails are delivered successfully by configuring your Libraesva Email Security Gateway (ESG).


Part 1: Whitelist System emails

Step 1: Log in to Libraesva

  • Navigate to your Libraesva ESG admin console.
  • Use an account with administrative privileges.

Step 2: Go to Whitelist Configuration

  • In the left-hand menu, go to:
  • Content Analysis → Whitelist/Blocklist

Step 3: Add a New Whitelist Entry

  • Click on "Add New" or the "+" icon.

Step 4: Enter Sender Details

  • In the “From Address”/Sender field, enter the following sending domains:
  1. mail.emailsupport.me
  2. mail.goldphish.com
  • In the “To Address” field, enter your recipient domain (e.g. @yourcompany.com) or leave it as default to include the entire domain.
  • Do not tick the “Check Envelope Only” box - leave it unchecked so the system examines both envelope and header data.

Our whitelisting technical information can be found here: Whitelisting Technical Information.
