如何从我的C＃应用程序发送电子邮件？ [英] How do I send an email message from my C# application?
问题描述
这是我写的代码：
MailMessage mail = new MailMessage("test@gmail.com", "me@myurl.com");
mail.Subject = "This is a test!!";
mail.Body = "testing...";
SmtpPermission connectAccess = new SmtpPermission(SmtpAccess.Connect);
System.Console.WriteLine("Access? " + connectAccess.Access);
SmtpClient client = new SmtpClient("mail.myurl.com", 2525);
client.Send(mail);
它不工作。我得到的线异常client.Send（邮件），上面写着邮箱不可用的服务器响应（MYLOCALCOMPUTERNAME）[我的本地IP]。3045目前不允许通过中继
It's not working. I get an exception at the line "client.Send(mail)" that says "Mailbox unavailable. The server response was (MYLOCALCOMPUTERNAME) [MY LOCAL IP]:3045 is currently not permitted to relay through."
connectAccess.Access不会返回连接（我不知道这是否是必要的......我在添加它来启动故障排除过程。）
connectAccess.Access does return "Connect" (I'm not sure if this was necessary... I added it in to start the troubleshooting process.)
这是否意味着我的本地机器以某种方式进行配置？什么时候我的应用程序部署到其他民族的机器？请问我们需要有本地配置呢？我只是希望创造一个发送反馈式的从我的应用程序链接
Does this mean that my local machine has to be configured in some way? What about when I deploy my app to other peoples machines? Will there need to be local configuration there? I'm just looking to create a "Send Feedback" type of link from my application.
（注：在我的实际应用中我用我的真实电子邮件地址均在到和从我的SMTP是真的在承载我的网址/网站的地方我的SMTP地址）
(Note: in my real application I am using my real email addresses in both the "to" and "from" and my smtp is really my smtp address at the place that hosts my url/website)
谢谢！

推荐答案
@迈克尔：感谢您的链接。这是非常有帮助的。
@ Michael: thanks for the link. It's very helpful.
我的认为的我想通了，我的问题。我需要我创造了我的客户对象之后，再添加登录凭据。我添加了以下行：
I think I figured out my problem. I did need to add the login credentials after I created my "client" object. I added the following line:
client.Credentials = new System.Net.NetworkCredential("myloginat+myurl.com", "mypassword");
（对不起 - 我有这个习惯后，我寻找一个答案在网络上，并通过我的手册2小时后，我终于打破和发布问题，然后在5分钟后看着办吧。:)我觉得写下来的问题的行为可以帮助我比什么都重要）
(sorry - I have this habit that after I search for an answer on the web and through my manuals for 2 hrs, I finally break down and post the question and then 5 minutes later figure it out. :) I think the act of writing down the question helps me more than anything else)
所以它的工作...虽然我不会要求我了解我如何以及为什么它的工作，所以希望我给予我的程序给他人使用在运行一些问题的一切。即，将每个人都使用具有互联网连接能够打开此SMTP连接到我的服务器的程序？我不知道这个问题的答案......我将不得不等待，看看，多学习一些。
So it's working... although I won't claim I understand everything about how and why it's working so I do expect to run in to some problems as I give my program to others to use. i.e., will everyone using the program that has an internet connection be able to open this smtp connection to my server? I don't know the answer to that... I'll have to wait, see, and learn some more.
谢谢！ ：）
