[SpamCop-List] How do I send emails to xenophobic paranoid Attorney General offices?

[brewman]

I'm trying to send a report about a website administered from Arizona
(hidden behind a facade so I can't use SC, unless I .. no, let's not
go there) to the Attorney General's office in Arizona, email address
aginquiries at ag <dot< state:az;us and getting bounced with 501
'Blocked by Filter 0'
I even tried postmaster@ and got same result. I emailed the US Embassy
here (New Zealand) and a similar thing happened.
Are the yanks really so paranoid about foreigners, or do they think
that allowing stuff from outside the borders of good ol' US of A is
tantamount to believing in SETI?
BTW I also tried from another ISP hosted in NZ and also got 501.
Anyone any ideas on how I can scale the ramparts and toss an email
into their midst?
