[GTER] Novo desafio contra o SPF: registros recursivos!

[Danton Nunes]

Descobri esta hoje:

$ spfquery -ip="ff02::1" -sender fulano at hecort.com
unknown

spfquery: error in processing during lookup of domain of hecort.com: 
Mechanisms used too many DNS lookups
Received-SPF: unknown (spfquery: error in processing during lookup of 
domain of hecort.com: Mechanisms used too many DNS lookups) 
client-ip=ff02::1; envelope-from=fulano at hecort.com;


Olhando para o registro vejo que ele é auto-recursivo, levando a um loop 
infinito:

"v=spf1 a mx ip4:148.244.114.131 ip4:148.244.114.53 include:hecort.com  all"

ideiazinha interessante essa!
