4 # NOTICE: Unless your version of sendmail is ancient, use the standard
5 # sendmail `FEATURE(dnsbl)' or `FEATURE(enhdnsbl)' and the hackmc script
6 # in the DCC source instead of this sendmail `FEATURE' file.

10 # Connect a DNS blacklist such as the RBL+ to the local DCCM daemon and so to
11 # a DCC server to report spam to the DCC database.
12 # The connection is by the sendmail "dcc_isspam" macro
13 #
14 # The first and required argument is the domain name of the DNS blacklist
15 # The second, optional argument is a log and SMTP status/rejection message.
16 #
17 # For example, with the following, mail from SMTP clients on the
18 # relays.mail-abuse.org list would be rejected as well as reported as
19 # extremely bulky to the DCC server:
20 # `FEATURE(dccdnsbl, `zen.spamhaus.org', `"Mail from " $`'&{client_addr} " reject to DCC - see http://www.spamhaus.org/zen/"')'
21 #
22 # (Of course, the outer pair of `' quotes must be removed)
23 #
24 # The `FEATURE(dccdnsbl)' line should be after the `FEATURE(dcc)' line
25 # if the latter is present.
26 #
27 # If you see error messages from sendmail like "map macro not found", check
28 # for the Kmacro definition in cf/m4/proto.m4 and consider the "dnl" comments
29 # below.
