Changing a correct mail robot only to bypass a broken Spam
filter makes no sense, fix the filter.  From = To is a valid
reason to tag mails, that's not the problem.  But that...

...is very dubious.  Dorkslayers.com WAS a block list listing
only non-US-servers for invalid reasons and without any way to
unlist a server.  The dorks were taken out of business by a
DDoS some weeks ago - good riddance - and you shouldn't see a
10.225.20.192.orbs.dorkslayers.com

192.20.225.10 is akpublic.research.att.com and not listed in
any blocklist, compare <URL:http://rbls.org/?q=192.20.225.10>
or check out `host 10.225.20.192.orbs.dorkslayers.com`

Maybe somebody at your system uses unreliable AND obsolete zone
files - without the dubious 2.2 ORBS points all would be okay.
