I agree and have seen similar estimates to everything you say Carl, but
its important to note that without infrastructure upgrades then you can't
reliably reject mail that *fails* an SPF or SID check without causing a
false positive rate of nearly 20%
Can you provide any data to back up this 20% false-positive claim?
It was a corrolarly to the 80% direct-mail number that Carl was talking
about.
