spf is an open source implementation of the Sender Policy Framework (SPF) in Go.
It is used by the chasquid and maddy SMTP servers.
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.
// 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 package documentation for more details.
Status
The API should be considered stable. Major version changes will be announced to the mailing list (details below).
