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.

Notice: do nnoott use mmaakkeemmaapp to create the aliases data base, but

nneewwaalliiaasseess which puts a special token into the data base that is

required by sseennddmmaaiill..

If the _T_r_u_s_t_e_d_U_s_e_r option is set in the sendmail configuration 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 sseennddmmaaiill 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 sendmail.cf ``K'' line.

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

--DD Use to specify the character to use to indicate a comment (which

is ignored) instead of the default of '#'.

--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 directo-

ries.

--tt Use the specified delimiter instead of white space (also for

dumping a map).

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

--vv Verbosely print what it is doing.
