I'm sure this works - but I don't understand how. Where did you come up
with that single IP address?

Betreff: [Assp-test] large domain SPF failures
-------------------------
We've received a quantity of junk impersonating good domains - not
sure
how to handle it.
An example: efax.com SPF record
v=spf1 mx include:_spf.salesforce.com -all
So they're depending on salesforce. Ok...what do they have?
v=spf1 include:_spf.google.com include:_spf.salesforce.com
include:spf.mandrillapp.com exists:%{i}._spf.corp.salesforce.com ~all
Now they check against google before their own, ok...
It just goes on and on. But the initial failure:
Maximum void DNS look-ups limit (2) exceeded.
Google is probably at fault - but as usual the biggest guy around gets
to do what they want.
Is there a way of accommodating these nonsense configs to still use
them
to block impersonators?
