Re: [ietf-smtp] SPF DNS query limits

BTW - do these companies just add all the IP addresses they own to their 
SPF records? Do Google really have ~230,000 mail servers?

No, but they certainly have thousands, way too many to enumerate in SPF records.

Just as a matter of interest - wouldn't it be worth them using macros in 
their includes? eg 'include:%{i4r}'. This could cut down 
drastically on the level of nesting.

Yuck.  That feels really fragile.
