Because "hosts" takes a "hostlist" as its argument, and "*-*-*-*" isn't
a valid item in a "hostlist"

http://www.exim.org/exim-html-current/doc/html/spec_html/ch10.html#SECThoslispatnam

"If a pattern starts with "*" the remainder of the item must match the
end of the host name. For example, *.b.c matches all hosts whose names
end in .b.c. This special simple form is provided because this is a very
common requirement. Other kinds of wildcarding require the use of a
regular expression."
