[spf](https://godoc.org/blitiri.com.ar/go/spf) is an open source
implementation of the Sender Policy Framework (SPF) in Go.
It is used by the [chasquid](https://blitiri.com.ar/p/chasquid/) SMTP server.
## Example
The API is quite simple: it has only one main function to perform the SPF
check, similar to the one suggested in the
[RFC](https://tools.ietf.org/html/rfc7208).
```go
// Check if `sender` is authorized to send from the given `ip`. The `domain`
// is used if the sender doesn't have one.
result, err := spf.CheckHostWithSender(ip, domain, sender)
if result == spf.Fail {
// Not authorized to use the domain.
}
```
See the [documentation](https://godoc.org/blitiri.com.ar/go/spf) for more
details.
## Status
The API should be considered stable. Major version changes will be announced
to the mailing list (details below).
## Contact
