Hi Justin,
Good point.  We added example.com by request, and we've just had
another request for example.tld.  Both are in the rfc-ignorant.org

Name:    example.com.abuse.rfc-ignorant.org

Name:    example.tld.abuse.rfc-ignorant.org

HOWEVER, *other RBLs* are not used to block on message bodies and
example.com is unlikely to be used as a sender domain.   But it
could appear in a message body URI as someone's example.

It's part of the reason we wanted to be conservative and use only
non-existent domains or ones we control as test points:

Name:    test.sc.surbl.org.sc.surbl.org

Name:    test.surbl.org.sc.surbl.org

Our currently having in the lists is probably safe
since unlike, .2 should probably never occur in emails
unless someone had an unusual loopback address URI to share.


Does anyone have any comments about whether we should remove
example.com from the test set?  Justin makes a valid point that
it could block messages with example URIs.  I'm leaning towards
taking it out.

If we do, anyone using example.com in their test URIs should
change to test.surbl.org or test.(zone).surbl.org.

Comments please,

Jeff C.
