You can use the code for extension method to save mailMessage ( from codeProject : Adding Save() functionality to System.Net.Mail.MailMessage )

MailMessageExt：

public static class MailMessageExt
    {
        public static void Save(this MailMessage Message, string FileName)
        {
            Assembly assembly = typeof(SmtpClient).Assembly;
            Type _mailWriterType =
              assembly.GetType("System.Net.Mail.MailWriter");

            using (FileStream _fileStream =
                   new FileStream(FileName, FileMode.Create))
            {
                // Get reflection info for MailWriter contructor
                ConstructorInfo _mailWriterContructor =
                    _mailWriterType.GetConstructor(
                        BindingFlags.Instance | BindingFlags.NonPublic,
                        null,
                        new Type[] { typeof(Stream) },
                        null);

                // Construct MailWriter object with our FileStream
                object _mailWriter =
                  _mailWriterContructor.Invoke(new object[] { _fileStream });

                // Get reflection info for Send() method on MailMessage
                MethodInfo _sendMethod =
                    typeof(MailMessage).GetMethod(
                        "Send",
                        BindingFlags.Instance | BindingFlags.NonPublic);

                //// Call method passing in MailWriter  -- before net 4.5 
                //_sendMethod.Invoke(
                //    Message,
                //    BindingFlags.Instance | BindingFlags.NonPublic,
                //    null,
                //    new object[] { _mailWriter, true },
                //    null);

                // Call method passing in MailWriter  --net 4.5 later
                _sendMethod.Invoke(
                      Message,
                       BindingFlags.Instance | BindingFlags.NonPublic,
                      null,
                    new object[] { _mailWriter, true, true },
                   null);

                // Finally get reflection info for Close() method on our MailWriter
                MethodInfo _closeMethod =
                    _mailWriter.GetType().GetMethod(
                        "Close",
                        BindingFlags.Instance | BindingFlags.NonPublic);

                // Call close method
                _closeMethod.Invoke(
                    _mailWriter,
                    BindingFlags.Instance | BindingFlags.NonPublic,
                    null,
                    new object[] { },
                    null);
            }
        }
    }

Call :

    MailMessage _testMail = new MailMessage();
            _testMail.Body = "This is a test email";
            _testMail.To.Add(new MailAddress("[e-mail]"));
            _testMail.From = new MailAddress("[e-mail]");
            _testMail.Subject = "Test email";
            _testMail.Save(@"D:\testemail.eml");

Best Regards,

Do you have Outlook installed on Server?
As I understand to use such DLL you need to have Outlook installed and configured.
