什么是发送电子邮件的大批量在ASP.NET的最好方法？ [英] What is the best way to send large batches of emails in ASP.NET?

问题描述

目前，我正在通过一个DataReader循环和调用System.Net.Mail.SmtpClient的send（）方法。与此问题是，它是缓慢的。每封电子邮件大约需要5-10秒发送（这是可能的，这是我的主机只是一个问题）。我不得不重写我的web.config文件中的executionTimeout默认值（默认为90秒）是这样的：

I'm currently looping through a datareader and calling the System.Net.Mail.SmtpClient's Send() method. The problem with this is that it's slow. Each email takes about 5-10 seconds to send (it's possible this is just an issue with my host). I had to override the executionTimeout default in my web.config file (it defaults to 90 seconds) like this:

 <httpRuntime executionTimeout="3000" />

警告：我是一个共享的主机上，所以我不认为这是可能对我使用PickupDirectoryFromIis选项（至少，它给了我错误，当我打开它）发送

One caveat: I'm on a shared host, so I don't think it is possible for me to send using the PickupDirectoryFromIis option (at least, it gave me errors when I turned it on).

推荐答案

您可以发送邮件异步的。这样的超时不应该打断你的发送。

You could send the mail asynchronous. That way the timeout should not interrupt your sending.

这个文章应该帮助您开始与：在C＃异步发送电子邮件。

This article should help you get started with that: Sending Emails Asynchronously in C#.

和关闭过程中有几个商业客户可用，但我都试过，可以推荐的唯一一个是的http：/ /www.aspnetemail.com/
