# redirect anything that hasn't been caught yet to me,
# based on
# http://blog.alteholz.eu/2015/04/exim4-and-catchall-email-address/
# that reference includes the lines allow_fail and allow_defer, but
# afaik, they are completely superfluous and just copied from another
# router, they apply when the expansion of data contains :defer: or :fail:,
# but we are just using a string literal.
