I propose that there should be a limit of, say, 4-8 DNS queries in
toto, for all levels of includes and redirects.  SPF implementations
MUST NOT query more than this.  I also think there should be a limit
to the number of bytes that will be parsed, and that limit be
something like 512-2048.

Wouldn't doing away with the macro-char t (also) greatly reduce the ddos risk?
What is t needed for, anyway?
