DOMESTIC MAIL MANUAL The  Domestic Mail Manual  (DMM) is our basic guide in the Military Postal Service.   It sets forth the regulations  and  procedures  governing  the  domestic mail services offered to the public by the USPS.  The DMM  consists  of  a  DMM  Utilities  that  gives step-by-step instructions on how to use the DMM, and the  12  subject  modules  (tab  dividers)  arranged  in alphabetical  order  except  for  the  Index.     These modules include:    A - Addressing    C - Characteristics and Content    D - Deposit, Collection, and Delivery    E - Eligibility    F - Forwarding and Related Services    G - General Information    L - Labeling Lists    M - Mail Preparation and Sortation    P - Postage and Payment Methods    R - Rates and Fees    S - Special Services    I - Index Information Material   in   the   DMM   is   organized   in   an alphanumeric numbering system.  At the top left-hand side of the page you will notice a number, which shows the first paragraph of that page.   The number, which appears  on  the  top  right-hand  side,  shows  the  last paragraph of that page. Look at the letters and numbers in figure 1-2.  The first  letter  “C”  refers  to  module  C.    The  next  three numbers identify the basic subject of module C; and “010"  refers  to  General  Mailability  Standards.   The fourth digit refers to a more specific subject called a part,  which,  in  this  example,  is  Part  2,  entitled ”Packaging."    The  fifth  and  final  digit  is  a  section, numbered   here   as   “1,”   referring   to   packaging adequacy.

INTERNATIONAL MAIL MANUAL The  International  Mail  Manual  (IMM)  contains detailed  information  concerning  international  postal rates. It  lists  special  mailing  prohibitions,  import restrictions, and other mailing conditions applicable to mail sent from an MPO or U.S. post office to a foreign country.   It  also  contains  individual  country  listings arranged alphabetically.   Since you must refer to the IMM for each article addressed to a foreign country, this  manual  will  be  discussed  in  detail  in  chapter  6.
