       makemap - create database maps for sendmail

       makemap  [-C  file]  [-N] [-c cachesize] [-d] [-e] [-f] [-l] [-o] [-r]
       [-s] [-t delim] [-u] [-v] maptype mapnam

       Makemap creates the database maps used by the  keyed  map  lookups  in
       sendmail(8).   It reads input from the standard input and outputs them
       to the indicated mapname.

       Depending on how it is compiled, makemap handles up to three different
       database formats, selected using the maptype parameter.  They may be

       btree  B-Tree format maps.  This requires the new Berkeley DB library.

       hash   Hash format maps.  This also requires the Berkeley DB  library.

       In  all  cases, makemap reads lines from the standard input consisting
       of two words separated by white space.  The first is the database key,
       the  second  is  the  value.   The value may contain ''%n'' strings to
       indicate parameter substitution.  Literal percents should  be  doubled
       (''%%'').  Blank lines and lines beginning with ''#'' are ignored.

       Notice:  do  not  use  makemap  to  create  the aliases data base, but
       newaliases which puts a special token  into  the  data  base  that  is
       required by sendmail.

       If  the  TrustedUser  option is set in the sendmail configuration file
       and makemap is invoked as root, the generated files will be  owned  by
       the specified TrustedUser.

       -C     Use  the  specified  sendmail configuration file for looking up
              the TrustedUser option.

       -N     Include the null byte that terminates strings in the map.  This
              must match the -N flag in the ''K'' line.

       -c     Use the specified hash and B-Tree cache size.

       -d     Allow  duplicate  keys  in the map.  This is only allowed on B-
              Tree format maps.  If two identical keys are  read,  they  will
              both be inserted into the map.

       -e     Allow empty value (right hand side).

       -f     Normally  all upper case letters in the key are folded to lower
              case.  This flag disables that behaviour.  This is intended  to
              mesh  with the -f flag in the K line in  The value
              is never case folded.

       -l     List supported map types.

       -o     Append to an old file.  This allows you to augment an  existing

       -r     Allow replacement of existing keys.  Normally makemap complains
              if you repeat a key, and does not do the insert.

       -s     Ignore safety checks on  maps  being  created.   This  includes
              checking   for   hard  or  symbolic  links  in  world  writable

       -t     Use the specified delimiter instead of white space.

       -u     dump (unmap) the content of the database to standard output.

       -v     Verbosely print what it is doing.
