Note that the border MX host for earthlink.net are operated by
a separate provider:
earthlink.net. IN MX 5 mx01.oxsus-vadesecure.net.
earthlink.net. IN MX 5 mx02.oxsus-vadesecure.net.
earthlink.net. IN MX 5 mx03.oxsus-vadesecure.net.
earthlink.net. IN MX 5 mx04.oxsus-vadesecure.net.
Otherwise known as Vade Secure:
https://www.vadesecure.com/en/
which likely means that "Vade Secure", not Earthlink implement the
underlying filtering methods. With sufficiently many 3rd-parties in the
forwarding chain, resolving issues can get complicated... :-(
I don't personally have any earthlink.net correspondents, so no direct
experience of either getting through or not.
