show sender name from mail headers in Apple Mail How to configure Apple Mail.app to show name from mail headers "From: " field and not from Contacts.app???

Apple Mail.app shows me always the name from Contacts.app (card is a read only download from global catalog), e.g.:


"Service Address" front-desk@ourcompany.net


But we have more than one who use this address. And this people configure there clients as follow:


name: "person1 first last" / address: front-desk@ourcompany.net
name: "person2 first last" / address: front-desk@ourcompany.net
name: "person3 first last" / address: front-desk@ourcompany.net


When I look to the mail headers, there are the correct names inside, but in Apple Mail.app the list view shows only:


"Service Address" front-desk@ourcompany.net


So I'm not able for differing the sender of mail without reading this.

And I do not want to manage a private address card for this address, because the people behind this address are changing all 4-6 weeks! The version I use before has done this correct, is El Captain a downgrade or have I to change to Thunderbird?
You can see the actual sender email address by clicking on the email, then clicking the small down arrow next to the sender name. The menu that appears has it grayed out at the top of the menu:
