Issue while working with DKIM

Hi,



We encountered also a problem with DKIM.

Encloses the Aspose code that’s not working and the code that is working on the same DKIM configuration using dkim.net.dll:



We use Aspose mail 6.1.0 also tried 5.9.0



public void StuurAsposeDKIMEmail()

{

try

{

Aspose.Email.License license = new Aspose.Email.License();

license.SetLicense(“Aspose.Total.lic”);

string privateKeyFile = @“C://Temp/EmailKey/06012016userv.pem”;

RSACryptoServiceProvider rsa = PemReader.GetPrivateKey(privateKeyFile);

DKIMSignatureInfo signInfo = new DKIMSignatureInfo(“06012016userv”, “userv.nl”);

signInfo.Headers.Add(“From”);

signInfo.Headers.Add(“To”);

signInfo.Headers.Add(“Subject”);

signInfo.BodyCanonicalization = CanonicalizationType.Simple;

signInfo.HeaderCanonicalization = CanonicalizationType.Simple;

signInfo.HashAlgorithm = DKIMHashAlgorithm.RSASha1;

MailMessage mailMessage = new MailMessage(“test@userv.nl”, textBox1.Text);

mailMessage.Subject = “DKIM test message”;

mailMessage.Body = “Test”;

MailMessage signedMsg = mailMessage.DKIMSign(rsa, signInfo);



using (SmtpClient client = new SmtpClient(“", 25, "*”, “******”))

{

client.Send(signedMsg);

}

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}

}



This is working with the enclosed attachment:



public void StuurDKIMTestMail()

{

try

{

var privateKey = PrivateKeySigner.LoadFromFile(@“C://Temp/EmailKey/06012016userv.pem”);

var DnsSelector = “06012016userv”;

var dkimSigner = new DkimSigner(privateKey, “userv.nl”, DnsSelector, new string[] { “From”, “To”, “Subject” });

var domainkey = new DomainKeySigner(privateKey, “userv.nl”, DnsSelector, new string[] { “From”, “To”, “Subject” });



System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();

msg.To.Add(textBox1.Text);

msg.Subject = “DKIM test message”;

msg.Body = “Hello world”;

msg.From = new System.Net.Mail.MailAddress(“test@userv.nl”);



msg.DomainKeySign(domainkey);

msg.DkimSign(dkimSigner);

using (System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient())

{

client.Port = 25;

client.Host = “***”;

client.Credentials = new System.Net.NetworkCredential("*", "");

client.Send(msg);

}

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}



}
