I'm looking for lists of domains to whitelist. Here's the criteria.

1) The host will be whitelisted based on RDNS of the IP where the RDNS
name matches the IP that was looked up.
2) That the domain never sends any spam.

So - not looking for mixed spam sources but pure ham sources. If the
hostname is on my list then whenever a host that resolves to that domain
hists one of my servers then that IP will be whitelisted. I also have a
really good whitelist that you can all use. Here's the rule:

header RCVD_IN_JMFILTER_W eval:check_rbl_sub('JMFILTER', '127.0.0.1')
describe RCVD_IN_JMFILTER_W Sender listed in JMFILTER-WHITE
tflags RCVD_IN_JMFILTER_W net nice
score RCVD_IN_JMFILTER_W -5


Any contribution is appreciated. If you have a big list that would be
great. Here's a short list as an example:
