That you very much for the almost exact pointer. I'd been trying
(unsuccessfully) to use the router or transport features to accomplish
this, as I hadn't had a reason to use the filter function of exim until
now.

For the archives, the exact[1] syntax I used is:

# Exim filter
if $h_X-Mailer: matches "broken vendor" then
headers remove Date
headers add "Date: $tod_full"
endif

[1] Ok, so it's not "broken vendor" :) Everything else is exact.
