mmaakkeemmaapp - create database maps for sendmail
SSYYNNOOPPSSIISS
mmaakkeemmaapp [--CC _f_i_l_e] [--NN] [--cc _c_a_c_h_e_s_i_z_e] [--dd] [--ee] [--ff] [--ll]

DDEESSCCRRIIPPTTIIOONN
MMaakkeemmaapp 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 _m_a_p_n_a_m_e_.
Depending on how it is compiled, mmaakkeemmaapp handles up to
three different database formats, selected using the _m_a_p_-
_t_y_p_e parameter. They may be
dbm DBM format maps. This requires the ndbm(3)
library.
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, mmaakkeemmaapp 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.
If the _T_r_u_s_t_e_d_U_s_e_r option is set in the sendmail configu-
ration file and mmaakkeemmaapp is invoked as root, the generated
files will be owned by the specified _T_r_u_s_t_e_d_U_s_e_r_.
FFllaaggss
--CC Use the specified sendmail configuration file for
looking up the TrustedUser option.
--NN Include the null byte that terminates strings in
the map. This must match the -N flag in the send-
mail.cf ``K'' line.
--cc Use the specified hash and B-Tree cache size.
--dd 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.
--ee Allow empty value (right hand side).

--ff 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 KK line in sendmail.cf. The value is
never case folded.
--ll List supported map types.
--oo Append to an old file. This allows you to augment
an existing file.
--rr Allow replacement of existing keys. Normally
mmaakkeemmaapp complains if you repeat a key, and does not
do the insert.
--ss Ignore safety checks on maps being created. This
includes checking for hard or symbolic links in
world writable directories.
--uu dump (unmap) the content of the database to stan-
dard output.
--vv Verbosely print what it is doing.
