If you have not installed the 'mind_reader_pcre' module it JF does what it is told to do. Adds the header. IOW - (look at some of the headers of posts to this list) Exim just doesn't care about pre-existing headers of the same title unless you program it to do so, as in: - looking for some sort of full/partial/wildcard match, branching accordingly - stripping or re-ordering headers. > > What happens if a message has "Precedence: list" and I do "add_header = > Precedence: junk"? > Would exim alter the existing header, No. > would exim add a second header or Yes. > would exim skip adding that header? > If you program it to, yes.
