The IP and hashes scores 21.8 for me.

besides the standard DCC_CHECK, I'm getting hits on the following
non-standard RBLs:

190.244.172.161 listed in hostkarma.junkemailfilter.com
190.244.172.161 listed in uceprotect-level2.dnsbl
190.244.172.161 listed in bb.barracudacentral.org
190.244.172.161 listed in ix.dnsbl.manitu.net
iXhash found @ ix.dnsbl.manitu.net

Maybe you had a DNS problem when it went through, or you were unlucky
enough to be first on the spammer's list.

Here's a (somewhat unreadable) rule I wrote that doesn't have a great
spam ratio on its own, but can be useful in botnet meta rules:

header NOMATCH_NICK_FROM        From =~
/^"?(([A-Z])[a-z][a-z])\w*(?:\s(?:(([A-Z])[a-z][a-z])\w*\s|([A-Z])\.?\s)?(([A-Z])[a-z][a-z])\w*)?"?\s*<(?![a-zA-Z1-9\.\-]*(?:\1|\3|\6))(?!.?\2(?:\4|\5)?.?\7).*?\@(?!.?\2-?(?:\4)?\-?\7)(?![a-zA-Z1-9\.\-]*(?:\1|\3|\6))(?!postmaster\@)(?!mailer-daemon\@)/i
describe NOMATCH_NICK_FROM      From address with no part of name
score NOMATCH_NICK_FROM         1.0

The idea is to catch random real names attached to random valid email
addresses.
