*REGULAR EXPRESSION TABLES*
This section describes how the table lookups change when
the table is given in the form of regular expressions. For
a description of regular expression lookup table syntax,
see*regexp_table*(5)<http://www.postfix.org/regexp_table.5.html>
or*pcre_table*(5)<http://www.postfix.org/pcre_table.5.html>.
Each pattern is a regular expression that is applied to
the entire string being looked up. Depending on the appli-
cation, that string is an entire client hostname, an
entire client IP address, or an entire mail address. Thus,
no parent domain or parent network search is done,
/u...@domain/ mail addresses are not broken up into their
/user@/ and/domain/ constituent parts, nor is/user+foo/ broken
up into/user/ and/foo/.
Patterns are applied in the order as specified in the ta-
ble, until a pattern is found that matches the search
string.
Actions are the same as with indexed file lookups, with
the additional feature that parenthesized substrings from
the pattern can be interpolated as*$1*,*$2* and so on.
I copied the entire section detailing PCRE access matches for you,
since you seem unable to find it.
Useless answer. If you had read my message, you would have seen that
I quoted from it.
And yet you didn't understand what it says.
It bears repeating.
How many domain names look like IP addresses to you ?
If check_client_access matches against both IPs and hostnames, then your
regex table will match against both IPs and hostnames.
This is not what the documentation says:
Depending on the application, that string is an entire client
hostname, an entire client IP address, or an entire mail address.
^^
It is said "or", and "or" doesn't mean "both". Quite the opposite.
If you combine
Each pattern is a regular expression that is applied to the entire string
being looked up.
with
*
check_client_access /type:table
<http://www.postfix.org/DATABASE_README.html>/*
Search the specified access database for the client hostname, parent
domains, client IP address, or networks obtained by stripping least
significant octets. See the access(5)
<http://www.postfix.org/access.5.html> manual page for details.
the result is as explained.
Nowhere in the entire documentation is it mentioned that a regex table
will ONLY match a domain OR an IP address.
If it's not in the manual, then it's not supported.
