But that shows that AOL, which is possibly the biggest ISP on the
planet, can fit under the 512 byte limit, so nobody else should have a
problem.
Not that I am in favor of XML but the include mechanism could still
be used to split things into smaller pieces if needed.

<include>

spf2.views-the-world-through-a-gui.com
</include>

I know its an additional lookup but I use include now so that I can
change one record if addresses change instead of thousands.
