No nicer ones, reformulating your suggestion in exim-filter syntax
to a string expansion seems to work, as far as my limited testing
shows.

matej@@ "${if eq {cepl@ISPdomain}{${address:$header_from:}} \
              {cepl@ISPdomain}fail}" Fs

i.e. if envelope from/sender is matej@primary hostname check whether
the address in the From:-header is cepl@ISPdomain and rewrite it to
cepl@ISPdomain, do nothing (fail) otherwise. (Paranoia setting would
use ${lc:...} on the domain.)
