Because there was no Golang package for Postmark’s spam API I decided to build one that can be easily used.
Example Usage
package main
import (
"github.com/psyb0t/go-spamcheck/spamcheck"
"fmt"
"encoding/json"
)
func main() {
rawEmail := `RAW EMAIL`
result := spamcheck.Check(rawEmail, true)
fmt.Println("Score:", result.Score)
rules, _ := json.MarshalIndent(result.Rules, "", " ")
fmt.Println("Rules:\n", string(rules))
fmt.Println("Report:\n", result.Report)
return
}Well that’s simple, right? This will have the following output format:
Score: 3.9
