To find out what types of lookup tables your Postfix system supports use the "ppoossttccoonnff --mm" command.
To test lookup tables, use the "ppoossttmmaapp --qq" command as described in the SYNOPSIS above.
The general form of a Postfix CIDR table is:
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 required.
IPv6 support is available in Postfix 2.2 and later.
Patterns are applied in the order as specified in the table, until a pattern is found that matches the search string.
