BUG: show full name-addr (RFC 5322) on receiver end

### Problem

See post #981 in the Discussions tab.

The sender address seen on the receiver end is the unprofessional "something@domain.xyz" instead of "User Name" < something@domain.xyz >

### Proposal

I would like is the "display-name" field to be added to the "angle-addr" field when sending the mail, so that the receiver sees a complete "name-addr". Currently, look at the picture in my first post #981 of the Discussions tab, what is seen on the receiver end is only the "addr-spec".
I read that this concatenation is not supposed to happen on the mail server, but on the client. And I don't seem to find where to configure this.
