I am pulling information from our Active Directory... however i am wanting to see which groups are internal or external.
So far on googling it seems that the
RequireSenderAuthenticationEnabled
is the switch to say if it external or extgernal.
What table and field in Active Directory is that information held.
Thanks
Chris

It's the msExchRequireAuthToSendTo attribute.
That attribute defines whether Exchange will reject emails from unauthenticated users.
"Unauthenticated" usually means "coming from outside your network", but not always. If an email is sent from inside your network via SMTP without authentication, it would still be rejected if that attribute is set to TRUE.
