Update on this subject for history sake:

Our version didn't use redirector and I thought it would work, but it doesn't
as redirector seem to fire up *before* you can check your "reply" so
redirector_access never gets desired arguments and nothing gets redirected.
However going by the lead from Amos here's what worked in my test lab:

error_directory /var/tmp/
# redirector_bypass off
acl plain_content rep_mime_type -i text/plain
http_reply_access deny plain_content

deny_info ERR_PLAIN_TEXT plain_content

where /var/tmp/ERR_PLAIN_TEXT is a plaintext file with a message for users.
