用ASP.NET Core 1.0中实现邮件发送功能

准备将一些项目迁移到 asp.net core 先从封装类库入手，在遇到邮件发送类时发现在 asp.net core 1.0中并示提供SMTP相关类库，于是网上一搜发现了MailKit

好东西一定要试一下，何况是开源，下面是代码可实现SMTP邮件发送：

using MailKit.Net.Smtp;
using MailKit.Security;
using MimeKit;
using System.Threading.Tasks;

namespace ConsoleApp1
{
    public class MailHelper
    {
        public static void Send(string email, string subject, string message)
        {
            var emailMessage = new MimeMessage();
            emailMessage.From.Add(new MailboxAddress("tianwei blogs", "mail@hantianwei.cn"));
            emailMessage.To.Add(new MailboxAddress("mail", email));
            emailMessage.Subject = subject;
            emailMessage.Body = new TextPart("plain") { Text = message };

            using (var client = new SmtpClient())
            {
                client.Connect("smtp.hantianwei.cn", , true);
                client.Authenticate("mail@hantianwei.cn", "******");

                client.Send(emailMessage);
                client.Disconnect(true);

            }
        }

        public static async Task SendEmailAsync(string email, string subject, string message)
        {
            var emailMessage = new MimeMessage();

            emailMessage.From.Add(new MailboxAddress("tianwei blogs", "mail@hantianwei.cn"));
            emailMessage.To.Add(new MailboxAddress("mail", email));
            emailMessage.Subject = subject;
            emailMessage.Body = new TextPart("plain") { Text = message };

            using (var client = new SmtpClient())
            {
                await client.ConnectAsync("smtp.hantianwei.cn", , SecureSocketOptions.None).ConfigureAwait(false);
                await client.AuthenticateAsync("mail@hantianwei.cn", "******");
                await client.SendAsync(emailMessage).ConfigureAwait(false);
                await client.DisconnectAsync(true).ConfigureAwait(false);

            }
        }

    }
}

以上代码同步异步都没有问题

注：一般邮箱如腾讯企业邮、163等都可以发送成功，但阿里云邮件推送失败，如果有高手可实现阿里云推送邮件请告诉我一下，非常感谢！
