Official Mail Management - S-1 Procedural Page

Role and responsibility

The Postal Officer manages official mail per DoDI 4525.09DODI 4525.09 and MCO 5110.4BMCO 5110.4B. The unit commander authorizes official mail processes and signs the official mail volume report. The S-1 officer supports the routing through the Postal Officer. The Marine drafting official correspondence applies official mail privileges per the document type. MPSA oversees the DoD-wide official mail program.

Source documents flow from the official correspondence (naval letters, memoranda, business letters), the mailing list, the penalty mail authorization per DoDI 4525.09 and 39 U.S.C., the paid postage requirement record, the mail volume data, and the audit findings. Outputs include the documented official mail authorization, the penalty mail processing record, the paid postage processing record, the volume tracking against MPSA reporting, the audited compliance record, the commander brief, and the SSIC-labeled records.

Per DoDI 4525.09 and 39 U.S.C., penalty mail authority allows federal agencies (including DoD) to send official mail at government expense. The privilege limits to official correspondence. Personal mail under penalty privileges is prohibited.
