Mail returned: What does "Sender not authorized per IS" mean?

[Whiskeygurl]

I got a letter back today saying return to sender not authorized per IS. Does anyone know what that means?

Are you an approved contact?

[Whiskeygurl]

Yes, I have been writing every day for the last several months

Ok, so apparently effective in May you can no longer use return address labels on the envelopes (which I have always used). That is why they returned my letter. All letters must be on white paper, in white envelopes and 100% hand written.

It may just be in Marion, where my friend is, but things don't have to be hand written. I have made "fliers," for him to hang up, containing some of our favorite quotes. Also, I have sent him information, he asked me to research, from the internet. I wonder if this is not a BOP "thing" but a prison-to-prison thing?

Possibly.....Leavenworth has proven to be quite difficult in getting stuff sent/recieved, etc.
