Legal Mail caselaw needed

I have been getting blocked from accessing the courts by mail due to my indigency and DACDC refusing to send out my legal mail to the courts. I have been writing 2-3 times per week to submit motions and add exhibits as evidence including 40 more mail rejection notices and 10 envelopes from the Supreme Court of New Mexico Law Library that were not processed properly as legal mail. Can you advise me on this or at least give me appropriate case law to cite in this regard?
