domain.tld IN TXT "v=spf1 redirect=_spf1.%{o}"
domain.tld IN TXT "spf2.0/mfrom,pra redirect=_spf2.%{o}"
domain.tld IN TXT "v=spf3 redirect=_spf3.%{o}"
That puts all that TXT data into a UDP packet - thus the "byteweight"
problem.
Correct, especially if there are other TXT records which have nothing to do
with either SPF or SenderID.
One suggesting that *would* help is the standard subdomain:
_spf.domain.tld IN SPF "v=spf3 ..."
Do we really want to make such changes to the protocol? I feel that we
should continue with the protocol as designed, using the momentum we now
have.
