You could also use check_rbl_headers
Add this to init.pre or in your favorite .pre file:
loadplugin Mail::SpamAssassin::Plugin::DNSEval
Then add this rule:
if (version >= 3.004003)
ifplugin Mail::SpamAssassin::Plugin::DNSEval
header HEADERBL_URIBL
It's actually just a domain name. This uridnsbl keys off domain names
in the body too, I was kinda hoping it would look at the domain names
in the headers like the body, guess not.
So there's an interesting history here. Back in the early/mid 2000s,
when SURBL, URIBL, and invaluement's URI
