Processing limits

This version changes the way of processing limits. Before the hard limit of 10 was done for all DNS lookup, but this causes many records to PermFail when processing MX mechanisms. Now the limit is done for mechanisms only (including "include" and "redirect") and retrieving A records for exchanges of MX mechanism will be limited to an additional 10 lookup.

This behaviour now matches the most popular implementations: read this StackOverflow answer for more information. There is no way of disable it and go back to previous way of processing limits.

Disable prefetch

• BC-BREAK Now DNS queries will be performed at evalution time. Previous checks that returned TempFail might now return another value on an early match. Old method can be re-activated with { prefetch: true } options.
• Now SPFResult contains the last mechanism matched (useful for Received-SPF header field "mechanism") and a list of all matched mechanisms in case that at least one "include" mechanism was processed.

Initial version

Tries to implement RFC4408.

• Missing ptr, exists, exp mechanisms.
• Missing resolve SPF DNS records before TXT ones.
• Missing domain specification (aka macros from section 8).
