# Package spf

[![Documentation](https://godoc.org/github.com/asggo/spf?status.svg)](http://godoc.org/github.com/asggo/spf)

Package spf parses an SPF record and determines if a given IP address

is allowed to send email based on that record. SPF handles all of the

mechanisms defined at http://www.open-spf.org/SPF_Record_Syntax/.

## Example

```Go

package main

import "github.com/asggo/spf"

func main() {

        SMTPClientIP := "1.1.1.1"

        envelopeFrom := "info@example.com"

        result, err := spf.SPFTest(SMTPClientIP, envelopeFrom)

        if err != nil {

                panic(err)

        }

        switch result {

        case spf.Pass:

                // allow action

        case spf.Fail:

                // deny action

        }

	//...

}

```
