External Address Verification (available and sold separately) allows IMail Administrators capability to use the IMail Server as a gateway to determine valid users on the destination server and reject all other recipients as invalid at the gateway.
This user verification process can be made by setting up an External Address Verifier. The External Address Verifier simply identifies users as valid or invalid.
The External Address Verifier is highly configurable, but currently only LDAP is supported as a verification database.
