Need Full- Name : in header

All versions

The F=x delivery agent flag is used by sendmail.cf header commands to force the inclusion of the user 's full name (F=):

 H?x?Full-Name: $x 

The F=x delivery agent flag has no special internal meaning to sendmail . It is a convention that is used only in the assorted Full-Name : header definitions (Full-Name:). See F= for a general description of this process.
