準備將一些項目遷移到 asp.net core 先從封裝類庫入手，在遇到郵件發送類時發現在 asp.net core 1.0中并示提供SMTP相關類庫，于是網上一搜發現了MailKit 

好東西一定要試一下，何況是開源，下面是代碼可實現SMTP郵件發送： 

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);       }  } }} 

以上代碼同步異步都沒有問題
 注：一般郵箱如騰訊企業郵、163等都可以發送成功，但阿里云郵件推送失敗，如果有高手可實現阿里云推送郵件請告訴我一下，非常感謝！
