As an alternative, you could use my MailKit library to send mail using Xamarin.iOS/Android/Mac.

public void SendSMTPMail(string from, string to, string subject, string body)
{
    var message = new MimeMessage ();
    var builder = new BodyBuilder ();

    message.From.Add (InternetAddress.Parse (from));
    message.To.Add (InternetAddress.Parse (to));
    message.Subject = subject;

    builder.TextBody = body;

    message.Body = builder.ToMessageBody ();

    using (var client = new SmtpClient ()) {
        client.ServerCertificateValidationCallback = (s, certificate, chain, sslPolicyErrors) => true;

        client.Connect ("mail.mydomain.gr", 25, false);
        client.Authenticate ("[email protected]", "mypass");
        client.Send (message);
        client.Disconnect (true);
    }
}
