Actually, I think the following series of commands are more helpful.
First the normal UDP request (with a fall-back to TCP):
[EMAIL PROTECTED]:~$ host -t txt aol.com
;; Warning: Message parser reports malformed message packet.
;; Truncated, retrying in TCP mode.
aol.com descriptive text "spf2.0/pra ip4:152.163.225.0/24 ip4:205.188.139.0/24
ip4:205.188.144.0/24 ip4:205.188.156.0/23 ip4:205.188.159.0/24
ip4:64.12.136.0/23 ip4:64.12.138.0/24 ip4:64.12.143.99/32 ip4:64.12.143.100/32
ip4:64.12.143.101/32 ptr:mx.aol.com ?all"
aol.com descriptive text "v=spf1 ip4:152.163.225.0/24 ip4:205.188.139.0/24
ip4:205.188.144.0/24 ip4:205.188.156.0/23 ip4:205.188.159.0/24
ip4:64.12.136.0/23 ip4:64.12.138.0/24 ip4:64.12.143.99/32 ip4:64.12.143.100/32
ip4:64.12.143.101/32 ptr:mx.aol.com ?all"
Then a direct TCP-only request, which works fine:
[EMAIL PROTECTED]:~$ host -T -t txt aol.com
aol.com descriptive text "spf2.0/pra ip4:152.163.225.0/24 ip4:205.188.139.0/24
ip4:205.188.144.0/24 ip4:205.188.156.0/23 ip4:205.188.159.0/24
ip4:64.12.136.0/23 ip4:64.12.138.0/24 ip4:64.12.143.99/32 ip4:64.12.143.100/32
ip4:64.12.143.101/32 ptr:mx.aol.com ?all"
aol.com descriptive text "v=spf1 ip4:152.163.225.0/24 ip4:205.188.139.0/24
ip4:205.188.144.0/24 ip4:205.188.156.0/23 ip4:205.188.159.0/24
ip4:64.12.136.0/23 ip4:64.12.138.0/24 ip4:64.12.143.99/32 ip4:64.12.143.100/32
ip4:64.12.143.101/32 ptr:mx.aol.com ?all"
Then on the same machine, asking spf.py to test an AOL address (using
the client IP address and HELO name from the Postfix log files):
[EMAIL PROTECTED]:~$ python /usr/share/python-support/python-spf/spf.py
64.12.138.200 [EMAIL PROTECTED] imr-m06.mx.aol.com
('temperror', 451, 'SPF Temporary Error: DNS Ran off end of data')
That's the same error I'm getting in the mail log. Then on the same
machine, asking spf.py just to get the AOL SPF records:
[EMAIL PROTECTED]:~$ python /usr/share/python-support/python-spf/spf.py aol.com
Traceback (most recent call last):
File "/usr/share/python-support/python-spf/spf.py", line 1621, in <module>
print q.dns_spf(sys.argv[1])
File "/usr/share/python-support/python-spf/spf.py", line 1010, in dns_spf
a = [t for t in self.dns_txt(domain) if RE_SPF.match(t)]
File "/usr/share/python-support/python-spf/spf.py", line 1045, in dns_txt
return [''.join(a) for a in self.dns(domainname, 'TXT')]
File "/usr/share/python-support/python-spf/spf.py", line 1150, in dns
for k, v in DNSLookup(name, qtype, self.strict):
File "/usr/share/python-support/python-spf/spf.py", line 105, in DNSLookup
raise TempError, 'DNS ' + str(x)
__main__.TempError: DNS Ran off end of data
I get the same thing running policyd-spf directly:
[EMAIL PROTECTED]:~$ policyd-spf
client_address=64.12.138.200
helo_name=imr-m06.mx.aol.com
[EMAIL PROTECTED]
[EMAIL PROTECTED]
action=defer_if_permit Received-SPF: Temperror (SPF Temporary Error: DNS
Ran off end of data) Mail From client-ip=64.12.138.200;
helo=imr-m06.mx.aol.com; [EMAIL PROTECTED];
[EMAIL PROTECTED];
Do you get the same results?
Thanks,
John
