发送电子邮件至 hotmail 收件箱
我正在尝试使用 c# MailMessage 向 hotmail 帐户发送电子邮件，但电子邮件总是变成垃圾邮件。
如何在 C# 中直接将电子邮件发送到 hotmail 收件箱？
我没有自己的 smtp 服务器，因此我尝试使用我的大学 smtp 和其他 smtp，如 google、yahoo...但所有电子邮件都被发送到垃圾邮件。
有什么解决办法吗？

这实际上并不是一个 C# 问题。
邮件会根据其内容和标题发送到垃圾邮件，因此您应该检查一些事项：
这些策略应该有助于您的电子邮件不被归类为垃圾邮件。
您始终可以检查其中一封垃圾邮件的标头。通常会描述应用了哪些规则以及邮件在何处失败。
This is not really a C# question.
Mails are sent to spam depending on their content and their headers so you should check a few things :
Using these strategies should help your email not being classified as spam.
You can always check the headers of one of the mail that went into spam. It is often described what rules were applied and where the mail failed.
在 hotmail 中，打开“垃圾邮件”文件夹，单击该邮件。 Hotmail 将在邮件正文中显示选项 - 单击“等等，很安全！” Hotmail 会将邮件移至您的收件箱，并将发件人电子邮件地址标记为安全。
您的代码（可能）没有任何问题 - 它是将发件人和/或主题识别为垃圾邮件的 hotmail。
In hotmail, open the Junk folder, click on the message. Hotmail will display options in the body of the message - click on "Wait, it's safe!" Hotmail will move the message to your inbox, and mark the FROM email address as safe.
There is (probably) nothing wrong with your code - it is hotmail identifying the sender and/or subject as being junk.
虽然垃圾邮件过滤器很可能超出您的控制范围，但通常在加权系统上工作，因此您可以采取一些措施来使您的电子邮件看起来不像垃圾邮件。
首先，请检查：
如果这些都很好，请查看此列表，live.com 上的这篇文章 和 Hotmail 的政策、实践和指南。
Although it may well be out of your control, junk email filters generally work on a weighting system, so there are things that you can do to make your email look less like spam.
To start with, check that:
If those are all fine, have a look through this list, this article on live.com and the Policies, Practices and Guidelines for Hotmail.
您的邮件内容是什么，是否是可能被垃圾邮件过滤器视为垃圾邮件的文本？您是否尝试过发送至其他帐户（例如 Yahoo 或 Gmail）？
What is the content of your mail, is it text that is likely to be regarded as junk mail by spam filters? Have you tried sending to other accounts such as Yahoo or Gmail?
你不能从 C# 做到这一点。
收件人可以将邮件路由到垃圾邮件箱或收件箱或决定将邮件放入的任何位置。如果允许发件人决定将邮件发送到客户端的何处，想象一下垃圾邮件的问题将会有多大。
您可以采用的一种解决方案是让您的目标邮件帐户将发件人列入“白名单”，但这可能并非在所有情况下都是一种选择。
You can't do it from C#.
It is up to the recipient to route the messages to junk or inbox or wherever it decides to put the message. If the sender were allowed to decide where the message went on the client's side, imagine how much bigger of a problem spam would be.
One solution you can employ is to have your target mail account 'whitelist' the sender, but that may not be an option in all cases.
