ASP.NET Core 1.0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", 465, 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", 25, 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！
