> So I need to get rid of the MX records for unfiltered.websiteworld.com?
As of right now, you don't have any active MX records for
unfiltered.websiteworld.com.
You have two redundant records for websiteworld.com:
websiteworld.com IN MX 10 mail.websiteworld.com
websiteworld.com IN MX 100 mail.websiteworld.com
You only need one of these.
For unfiltered, you have active only an A record:
unfiltered.websiteworld.com IN A 216.23.168.147
So mail will end up going to the A record. Adding an actual MX instead
for unfiltered is a good idea. Either way, a smart spammer could well
figure out that if the subdomain unfiltered.websiteworld.com exists,
that sounds a good place to send spam, so you need to keep this as
private as possible (not from client DNS queries, where it
realistically has to be published to route mail, but in any other
communication, including ensuring that zone transfers are not allowed
and not listing such addresses on the web).
