DESCRIPTIONmakemap creates the database maps used by the keyed map lookups in
sendmail(1M). makemap reads from the standard input and outputs to the
In all cases, makemap reads lines from the standard input consisting of
two words separated by whitespace. The first is the database key, the
second is the value. The value may contain %n strings to indicated
parameter substitution. Literal percents should be doubled (%%). Blank
lines and lines beginning with # are ignored.
makemap handles three different database formats. Database format is
selected using the maptype parameter. See OPERANDS.
The following options are supported:
Use the specified hash and B-Tree cache size (cache‐
Use the specified sendmail configuration file (file)
for looking up the TrustedUser option.
Allow duplicate keys in the map. This is only allowed
on B-Tree format maps. If two identical keys are
read, both be inserted into the map.
Use the specified character to indicate a comment
(which is ignored) instead of the default of '#'.
Allow empty value (right hand side).
Normally, all upper case letters in the key are
folded to lower case. This flag disables that behav‐
ior. This is intended to mesh with the -f flag in the
K line in sendmail.cf. The value is never case
List supported map types.
Include the null byte that terminates strings in the
map. This must match the -N flag in the K line in

complains if you repeat a key, and does not do the
Ignore safety checks on maps being created. This
includes checking for hard or symbolic links in world

Dump (unmap) the content of the database to standard
output. Note that, if the -t option is also provided,
the specified delimiter is used when the content is
dumped instead of whitespace.

The following operands are supported:
File name of the database map being created.
Specifies the database format. The following maptype parame‐
ters are available:
Specifies DBM format maps.
Specifies B-Tree format maps.
Specifies hash format maps.
