Return SPF data on TooManyDNSLookups or option to ignore TooManyDNSLookups

[sn-seanh]

Hey,

It would be great if the except for TooManyDNSLookups still returned the SPF and parsed SPF data so we can use it to identify which includes are causing too many look ups.

I see this similar feature was mentioned here - #18. However the return data only returns how many look ups were done.

Alternatively, an ignore TooManyDNSLookups might also be useful.

Thanks,
Sean
