The input and output /* file formats are expected to be compatible with: /* /* .nf /* \fBmakemap \fIfile_type\fR \fIfile_name\fR < \fIfile_name\fR /* .fi /* /* If the result files do not exist they will be created with the /* same group and other read permissions as their source file. /* /* While the table update is in progress, signal delivery is /* postponed, and an exclusive, advisory, lock is placed on the /* entire table, in order to avoid surprises in spectator /* processes. /* INPUT FILE FORMAT /* .ad /* .fi /* The format of a lookup table input file is as follows: /* .IP \(bu /* A table entry has the form /* .sp /* .nf /* \fIkey\fR whitespace \fIvalue\fR /* .fi /* .IP \(bu /* Empty lines and whitespace-only lines are ignored, as /* are lines whose first non-whitespace character is a `#'. /* .IP \(bu /* A logical line starts with non-whitespace text. A line that /* starts with whitespace continues a logical line. /* .PP /* The \fIkey\fR and \fIvalue\fR are processed as is, except that /* surrounding white space is stripped off. Unlike with Postfix alias /* databases, quotes cannot be used to protect lookup keys that contain /* special characters such as `#' or whitespace. /* /* By default the lookup key is mapped to lowercase to make /* the lookups case insensitive; as of Postfix 2.3 this case /* folding happens only with tables whose lookup keys are /* fixed-case strings such as btree:, dbm: or hash:. With /* earlier versions, the lookup key is folded even with tables /* where a lookup field can match both upper and lower case /* text, such as regexp: and pcre:. This resulted in loss of /* information with $\fInumber\fR substitutions. /* COMMAND-LINE ARGUMENTS /* .ad /* .fi /* .IP \fB-b\fR /* Enable message body query mode. When reading lookup keys /* from standard input with "\fB-q -\fR", process the input /* as if it is an email message in RFC 2822 format. Each line /* of body content becomes one lookup key. /* .sp /* By default, the \fB-b\fR option starts generating lookup /* keys at the first non-header line, and stops when the end /* of the message is reached. /* To simulate \fBbody_checks\fR(5) processing, enable MIME /* parsing with \fB-m\fR. With this, the \fB-b\fR option /* generates no body-style lookup keys for attachment MIME /* headers and for attached message/* headers. /* .sp /* This feature is available in Postfix version 2.6 and later. /* .IP "\fB-c \fIconfig_dir\fR" /* Read the \fBmain.cf\fR configuration file in the named directory /* instead of the default configuration directory. /* .IP "\fB-d \fIkey\fR" /* Search the specified maps for \fIkey\fR and remove one entry per map. /* The exit status is zero when the requested information was found. /* /* If a key value of \fB-\fR is specified, the program reads key /* values from the standard input stream.

When reading lookup keys /* from standard input with "\fB-q -\fR", process the input /* as if it is an email message in RFC 2822 format. Each /* logical header line becomes one lookup key.

By default, \fBpostmap\fR(1) does whatever /* is the default for /* the host operating system. /* .IP \fB-o\fR /* Do not release root privileges when processing a non-root /* input file. By default, \fBpostmap\fR(1) drops root privileges /* and runs as the source file owner instead. /* .IP \fB-p\fR /* Do not inherit the file access permissions from the input file /* when creating a new file.
