Why create such an obfuscation?
Why not just do the obvious and much more proper (despite the recent
relaxation mentioned elsewhere):
foo.friends.dom. IN MX 10 bar.my.dom.
bar.my.dom. IN MX 10 bar.my.dom.
This shows the true intent and makes it very clear that foo.friends.don
is a proper e-mail domain.
It also makes it a _lot_ easier to figure out what's going on if the
mailer at bar.my.dom suddenly complains that an MX points to itself!
