Product(s): Enterprise Vault

Problem

When classifying using "Number of Recipients" in VIC, messages that contain DLs may be incorrectly tagged.

Cause

DL expansion logic for SMTP-journaled emails is not triggered for custom message types. As a result, the NREA count is incorrect because DLs are treated as a single entity.

Solution

The following registry key must be configured according to the customer’s setup:

Registry Name: CustomMessageTypes

Location: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\KVS\Enterprise Vault\Storage

Type: REG_SZ (String)

Value: A comma-separated list of all custom message types (for example: SMTP.Email,Email,e-mail)

Fixed in EV 15.2.3 and EV 16.0
