a) Mail shall be delivered and posted promptly.
b) Offenders may correspond with anyone in the free community in accordance with this Subpart without prior written approval of the Chief Administrative Officer, except with employees, former employees, or releasees of the Department.

c) Each facility shall establish procedures in cooperation with the local post office for processing certified or registered mail. To send certified or registered mail, offenders must have sufficient funds in their trust fund accounts and must attach to the envelopes signed money vouchers so that the proper postage may be applied and the amount deducted from their trust fund accounts.
d) Offenders shall not be permitted to open, read, or deliver another offender's mail without the person's permission. However, offenders may transport mail in sacks or other closed containers under the direct supervision of an employee.
e) No disciplinary restrictions shall be placed on an offender's mail privileges.
