Defining which addresses are internal

You can specify internal domains using the InternalSMTPDomains registry key.

To add domains using the registry key, do the following on each computer with an Enterprise Vault Journaling task

Start Regedit and navigate to the following location:

HKEY_LOCAL_MACHINE
\Software
 \KVS
  \Enterprise Vault
   \Agents

Create a new String Value called InternalSMTPDomains.
Modify the key and in the Value Data field enter the required domains as a semicolon delimited string. For example, setting this string to the following means that addresses such as jld@eng.uk.ourcompanyinc.com and kv@hq.ourcompany.parentcorp.com will also be treated as internal:
```
	"ourcompanyplc.com; ourcompanyinc.com;
	ourcompany.parentcorp.com"
```
