I would like to setup rules in my GW 2014 client and therefore have to distinguish between internal and external mails. I have learned that there is a field named "view name" (in German "Anzg") that shows "Internet" when the mail is received from external sources.

Here it comes: when creating a new rule that field name doesn't show up even if I display all available fields.

Is there another way to create rules only for internal or external mails?
Or is there another way to identify internal mails? Because when it comes to internal mails the "from" field shows only name and surname of the sender but not the internal mail address. So I can't filter on "mydomain.com".

Any ideas?
