Solution

If you do not use ESET Remote Administrator to manage your network

Perform these steps on individual client workstations

Whitelisting or blacklisting using ESET Remote Administrator 5.x

A comma-delimited list of whitelist or blacklist items can be added via ESET Configuration Editor to more conveniently add multiple entries to the ESET Mail Security for Microsoft Exchange Server (EMSX) Allowed Senders/Blocked Senders lists. To do so, follow the steps below: 

  1. Open the ESET Remote Administrator Console (ERAC) by clicking Start → All Programs → ESET → ESET Remote Administrator Console → ESET Remote Administrator Console.
     
  2. Click Tools → Policy Manager.
     
  3. Select the policy that you want to modify and click Edit.
     
  4. Expand Windows Server v4.5 → Mail Security 4.5 for MS Exchange Server → Server protection → General mail server protection settings → Antispam protection → Antispam engine setup → Filtering and click Allowed senders list (WhiteList) or Blocked senders list (BlackList) depending on which list you want to add to.
     
  5. Click Console → Yes to save your changes. You can now export the entire configuration as an .xml file and import it directly into ESET Mail Security for Microsoft Exchange Server, or push the configuration out using ERAC.
