Adding RBLs to sendmail

[A. Eijkhoudt]

Hi Hendrik,

This feature has actually been in Sendmail for a very long time - at 
least since 2001, judging from a quick Google search.

Additionally, you might consider adding these as well; we use quite an 
extensive sendmail.mc with lots of additional milters for SPF, ClamAV, 
SpamAssassin...

FEATURE(`dnsbl', `relays.ordb.org',        `"554 Rejected " 
$&{client_addr} " found in relays.ordb.org"')dnl
FEATURE(`dnsbl', `bl.spamcop.net',         `"554 Rejected " 
$&{client_addr} " found in bl.spamcop.net"')dnl
FEATURE(`dnsbl', `sbl.spamhaus.org',       `"554 Rejected " 
$&{client_addr} " found in sbl.spamhaus.org/"')dnl
FEATURE(`dnsbl', `chinanet.blackholes.us', `"554 Rejected " 
$&{client_addr} " found in chinanet.blackholes.us"')dnl

Regards,
