Issue/Introduction

I have a list of domains that I would like to use for a Directory Group Matching (DGM). Can I index the domain instead of exact email addresses?

Resolution

Directory Group Matching (DGM) requires an exact match, which means that you must have the full e-mail address.  You cannot index just the domains.
