用ASP.NET Core 1.0中實現郵件發送功能

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如今 asp.net core 1.0中並示提供SMTP相關類庫，因而網上一搜發現了MailKit

好東西必定要試一下，況且是開源，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：通常郵箱如騰訊企業郵、163等均可以發送成功，但阿里雲郵件推送失敗，若是有高手可實現阿里雲推送郵件請告訴我一下，很是感謝！
