MX Lookup Mail Server Domain by Email Address

How to find the mail server for a given email address. Returns the domain name of the primary mail server. Go

    success := false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    dns := chilkat.NewDns()
    json := chilkat.NewJsonObject()

    emailAddr := "bob@example.com"

    // This gets all MX domains for an email address.  (Typically one domain.)
    // The preferred domain will be at index 0 (see below).
    success = dns.Query("MX",emailAddr,json)
    if success == false {
        fmt.Println(dns.LastErrorText())
        dns.DisposeDns()
        json.DisposeJsonObject()
        return
    }

    i := 0
    count_i := json.SizeOfArray("answer.mx")
    for i < count_i {
        json.SetI(i)
        domain := json.StringOf("answer.mx[i].domain")
        fmt.Println(*domain)
        i = i + 1
    }


    dns.DisposeDns()
    json.DisposeJsonObject()
