Description Mark Shaw 2003-05-31 11:32:38 UTC
Many spammer's web sites are alread listed by SBL or other DNSBLs,
while the spam source is a random abused proxy. Is it possible to add
DNSBL tests based on IP addresses of hosts in the message body, both
those mentioned in URLs and possibly those that are MX for domains
in e-mail addresses (remove, sales, etc)?

There's an existing bug for URL tests.

2.60-cvs already tests From: address domains.

I tried testing mailto: in addition to the From: addresses and the results
are iffy:

before:  4.406  10.7944   0.0622    0.994   0.93    1.00  DNS_FROM_RFCI_DSN
after:   7.200  14.2000   0.2000    0.986   0.90    1.00  DNS_FROM_RFCI_DSN

the delta: 3.40% SPAM, 0.1378% HAM = S/O ratio of 0.96

Could be better, so we'll just stick with the current DSN test for now.
