this is bad definition.

there is suposed to be up to 10 dns queryes and there were probably some more 
in previous includes.

Subject: [spf-discuss] SPF setup and recursion



My server flagged a message from paypal.com for non-compliance of
SPF...below is paypal's record.

paypal.com      text = "v=spf1 mx include:s._spf.ebay.com
include:m._spf.ebay.com include:p._spf.ebay.com include:c._spf.ebay.com
~all"
paypal.com      text = "spf2.0/pra mx include:s._sid.ebay.com
include:m._sid.ebay.com include:p._sid.ebay.com include:c._sid.ebay.com
~all"


Mail was sent from outbound2.den.paypal.com [216.113.188.112])


If you do a TXT lookup on c._spf.ebay.com it displays the following:

"v=spf1 ip4:12.155.144.75 ip4:62.22.61.131 ip4:63.104.149.126
ip4:64.68.79.253 ip4:64.94.204.222 ip4:66.135.215.134 ip4:67.72.12.29
include:c2._spf.ebay.com ~all"

Then you do a lookup on c2._spf.ebay.com's TXT:

"v=spf1 ip4:80.93.9.10 ip4:195.234.136.12 ip4:203.49.69.114
ip4:209.63.28.11 ip4:210.80.80.136 ip4:212.110.10.2 ip4:212.147.136.123
include:c3._spf.ebay.com ~all"

Then on c3._spf.ebay.com's TXT

"v=spf1 ip4:213.219.8.227 ip4:216.113.168.128 ip4:216.113.175.128
ip4:216.177.178.3 ip4:217.149.33.234 ip4:220.248.6.124 ip4:67.72.12.30
include:c4._spf.ebay.com ~all"

Lastly the Sender IP is on c4._spf.ebay.com:

"v=spf1 ip4:216.113.188.112 ip4:80.66.137.58 ip4:212.208.64.34
ip4:216.113.188.96 ~all"


Question: Does SPF allow recursions? If so, to what extent?

Thanks
