Transition from MailMan.MxLookupAll to the Chilkat DNS class

Provides instructions for replacing deprecated MxLookupAll method calls with the Chilkat Dns class. C#

bool success = false;

Chilkat.MailMan mailman = new Chilkat.MailMan();

// ...
// ...

string emailAddr = "joe@example.com";

// ------------------------------------------------------------------------
// The MxLookupAll method is deprecated:

Chilkat.StringArray sa = mailman.MxLookupAll(emailAddr);
if (mailman.LastMethodSuccess == false) {
    Debug.WriteLine(mailman.LastErrorText);
    return;
}

// ...
// ...

// ------------------------------------------------------------------------
// Do the equivalent using the Chilkat DNS class

Chilkat.Dns dns = new Chilkat.Dns();

Chilkat.JsonObject json = new Chilkat.JsonObject();

// 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) {
    Debug.WriteLine(dns.LastErrorText);
    return;
}

int i = 0;
int count_i = json.SizeOfArray("answer.mx");
while (i < count_i) {
    json.I = i;
    string domain = json.StringOf("answer.mx[i].domain");
    Debug.WriteLine(domain);
    i = i + 1;
}
