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！
