Wide-Open MADRID

2004-05-28 10:33:15

Lets say that Joe Jobs has an SPF record of: "v=spf1 mx ptr
ip4:69.0.0.0/7 -all"

 This is a valid record, and since he is coming from: 69.87.x.x it is
acceptable.  But now I find out he is a spammer. I can't block
69.0.0.0/7 so now I am stuck denying specific IP's again.

 Has this been discussed already and maybe I missed it (completely
possible)

 If not, maybe we can call any CIDR under /24 invalid?
Or find some way to validate the SPF netblock they list?

 I notice AOL is a /24 but many spammers on the list I created for
"Measuring MADRID" are a /19.

Thus it came to pass that Microsoft's multi-billion dollar "commitment"
to mail technologies was brought to a halt by the overwhelming and
incomprehensible demands of a UI widget that could display an RR to the
system administrator.
