[1: Followup-To set to news:comp.mail.sendmail ]
[2: The code presented should be considered to be ALPHA quality ]

I would like to present FEATURE(`anfi/rsdnsbl.m4') that is supposed to
fine tune set of DNSBL checks based on originating IP address
* reputation (using e.g. l2.apews.org )
* country (using e.g. zz.countries.nerd.dk )

The FEATURE itself does not block anything - it only decides if the
remaining/further DNSBL tests [FEATURE(enhdnsbl) tests] should be
skipped or conducted.

Sample1 - user in Poland:
#v+
dnl import IP addresses used to represent countries in
dnl zz.countries.nerd.dk in form C2_*
FEATURE(`anfi/countries')dnl

dnl first batch of enhdnsbl tests

dnl skip remaning test for PL, DE, UK and FR adresses
FEATURE(`anfi/rsdnsbl',`zz.countries.nerd.dk',`whitelist',`',
C2_PL, C2_DE, C2_UK, C2_FR)dnl

dnl second batch of enhdnsbl tests

dnl do remaning test only for CN and KR, do not test on TMP problems
FEATURE(`anfi/rsdnsbl',`zz.countries.nerd.dk',`blacklist',`t',
C2_CN, C2_KR)dnl

dnl third batch of enhdnsbl tests

Sample2 - user in Finland:
#v+
dnl import IP addresses used to represent countries in
dnl zz.countries.nerd.dk in form C2_*
FEATURE(`anfi/countries')dnl

dnl first batch of enhdnsbl tests

dnl skip remaning test for FI addresses
FEATURE(`anfi/rsdnsbl',`zz.countries.nerd.dk',`whitelist',`', C2_FI)dnl

dnl second batch of enhdnsbl tests

dnl do remaning test only for addresses listed in APEWS, do not test on TMP problems
FEATURE(`anfi/rsdnsbl',`l2.apews.org',`blacklist',`t')dnl

dnl third batch of enhdnsbl tests
