The default value for ~org-html-postamble~ is ~auto~, which makes the
HTML exporter build a postamble from looking up author's name, email

insert the postamble in the format specified in the
~org-html-postamble-format~ variable. The HTML exporter does not
insert a postamble if ~org-html-postamble~ is set to ~nil~.
