Prior to this improvement, when checking to see if an email was from an "Internal User", the matching document in $user view was required to have a FullName field.

Emails from 3rd party application may use a "from" address as a Group, Group documents in the address book do not contain a FullName field.

If no FullName field was found Crossware Mail Signature would log the following message:

ISINTERNALUSER-Failed to get fullname from NAMEGetItemText for key ''

With this change, if there is no FullName field, the application will use the from/principal field in determining group membership or when using the (!username!) lookup.

This change was implemented in V4.02.
