17.8 Configuration File Feature Reference | 629
This allows anything.cs.berkeley.edu to be treated differently from cs.berkeley.edu. For
example:
.cs.berkeley.edu REJECT
cs.berkeley.edu OK
Here, anything that ends in .cs.berkeley.edu will be rejected, whereas anything ending in
cs.berkeley.edu will be accepted.
Note that this FEATURE(lookupdotdomain) requires that the access.db be declared first. If
you reverse the declarations (this feature first), you will get the following warning and your
resulting configuration file will not be what you expect:
*** ERROR: FEATURE(`lookupdotdomain') requires FEATURE(`access_db')
Also note that this FEATURE(lookupdotdomain) should not be used in conjunction with the
FEATURE(relay_hosts_only) (?§7.4.6 on page 273) because that feature disables subdomain
lookups. If you declare FEATURE(relay_hosts_only) first and then declare this feature, the
following warning will be printed:
*** WARNING: FEATURE(`lookupdotdomain') does not work well with FEATURE(`relay_hosts_
only')
If you declare this feature first, then FEATURE(relay_hosts_only), no warning will be
printed.
17.8.27 FEATURE(loose_relay_check)
Allow %-hack relaying V8.
