Well, yes, but I guess I was assuming that you could have a text
record in the 450-500 byte range (depending on other DNS data). Text
records that go beyond that size I had assumed would switch to TCP.
The point is that instead of having a recommendation that SPF records
SHOULD be well below 500 bytes, I have learned that SPF MUST be below
256 bytes. And that means that AOL can't double the size of their SPF
record without breaking it up with include: mechanisms.
If so it might make sense to shorten the include modifier tag to
avoid recursion.
I think we need to accept that DNS is not the ideal vehicle here, but
it is at this stage all that we have.
