More or less (I make no comment on quite how sensible the particular
list you cite is !). I'd be careful about no 3 though. Many of the
so-called rogue headers are very particular so I would refrain from
interpolating too much otherwise you may bounce OK stuff.
If you had those headers in a text file of their own you could use perl
to generate a series of regexps to be cut and paste into
(global_)taboo_headers:
perl -n -e 'chop; s/(\W)/\\$1/g; print "/$_/i\n";' < headers.txt \
>taboo.txt

Not possible unless you are prepared to hack resend. Though you could
cheat and put a comment in each regexp so the text you wanted appeared
in the subject line of the bounced message. It would make the subject
line rather large though.
eg rather than
$global_taboo_headers = <<'END';
/^A-Bad-Header: Spam/i
END
do
$global_taboo_headers = <<'END';
/(?# *** WARNING THIS MAY BE SPAM ***)^A-Bad-Header: Spam/i
END
> $admin_headers = <<'END';

No need to add the expressions to $admin_headers. global_taboo_headers
is enough.
