# DESCRIPTION

2005-08-19 01:00:20 +04:00
|
|
|
# The Postfix mail system uses optional lookup tables.
|
|
|
|
|
# These tables are usually in \fBdbm\fR or \fBdb\fR format.
|
|
|
|
|
# Alternatively, lookup tables can be specified in CIDR
|

|
|
|
# (Classless Inter-Domain Routing) form.
|
|
|
|
|
#
|
|
|
|
|
# To find out what types of lookup tables your Postfix system
|
2005-08-19 01:00:20 +04:00
|
|
|
# supports use the "\fBpostconf -m\fR" command.

|
# The general form of a Postfix CIDR table is:
|
|
|
|
|
# .IP "\fInetwork_address\fB/\fInetwork_mask result\fR"
|
|
|
|
|
# When a search string matches the specified network block,
|
|
|
|
|
# use the corresponding \fIresult\fR value. Specify
|
2005-08-19 01:00:20 +04:00
|
|
|
# 0.0.0.0/0 to match every IPv4 address, and ::/0 to match
|
|
|
|
|
# every IPv6 address.
|
|
|
|
|
#
|
|
|
|
|
# An IPv4 network address is a sequence of four decimal octets
|
|
|
|
|
# separated by ".", and an IPv6 network address is a sequence
|
|
|
|
|
# of three to eight hexadecimal octet pairs separated by ":".
|
|
|
|
|
#
|
|
|
|
|
# Before comparisons are made, lookup keys and table entries
|
|
|
|
|
# are converted from string to binary. Therefore table entries
|
|
|
|
|
# will be matched regardless of redundant zero characters.
|
|
|
|
|
#
|
|
|
|
|
# Note: address information may be enclosed inside "[]" but
|
|
|
|
|
# this form is not recommended.
|
|
|
|
|
#
|
|
|
|
|
# IPv6 support is available in Postfix 2.2 and later.

# .IP "\fInetwork_address result\fR"
|
|
|
|
|
# When a search string matches the specified network address,
|
|
|
|
|
# use the corresponding \fIresult\fR value.
|
|
|
|
|
# .IP "blank lines and comments"
|
|
|
|
|
# Empty lines and whitespace-only lines are ignored, as
|
|
|
|
|
# are lines whose first non-whitespace character is a `#'.
|
|
|
|
|
# .IP "multi-line text"
|
|
|
|
|
# A logical line starts with non-whitespace text. A line that
|
|
|
|
|
# starts with whitespace continues a logical line.
