README
¶
Borrowed and refactored from daniellockard/gospfquery, to remove log.Fatal calls and make it more library-ish.
As explained in daniellockard's original Readme:
This does not implement REDIRECT, PTR, or EXISTS. The checking for the "ALL" record is very rough. It also turns all IPv6 records that lack a hostmask into a /128, because I don't know anything about IPv6 addresses. It turns IP4: records without a hostmask into a /32.

Variables ¶
var ( // ErrNoSPFRecords when no TXT/SPF records are found or parsed. ErrNoSPFRecords = errors.New("No SPF Records found.") )
Functions ¶
func GetDomainFromEmail ¶
GetDomainFromEmail returns the domain name from an email address. It is somewhat naive at present.
func NewSPFChecker ¶
func NewSPFChecker() *spfChecker
NewSPFChecker returns a SPF looker-upper with an internal cache. You should probably use the library's instance through the top-level functions.
func Validate ¶
Validate returns whether emails from a domain can be sent from a given IP. This is the intended main entry point to this library. If you have an email address, then use GetDomainFromEmail to get the domain. Results from Validate are simply cached in RAM; extended and heavy use may create a memory leak. If this is a problem, simply call the top-level DumpCache function.
