rfc-ignorant.org has shutdown.

If you are seeing lame_server resolving messages with rfc-ignorant in your logs this might help. I tried this on version 6 and 7.

named[2811]: lame server resolving 'progressivebusinessgifts.com.fulldom.rfc-ignorant.org' (in 'fulldom.rfc-ignorant.org'?):

The message is originating out of spamassassin.

I located the check in /opt/zimbra/conf/spamassassin/20_dnsbl_tests.cf

I commented out the 2 lines about ___RFC_IGNORANT_ENVFROM

su - zimbra
% zmamavisdctl restart

There might be a better way but that is how I did it.
