推荐答案
你几乎肯定也需要授权：现在几乎没有电子邮件系统被配置为允许匿名用户发送电子邮件。
看看这个：使用或不使用附件在C＃中发送电子邮件：通用例程。 [ ^ ] - 我知道它有效，因为它是我使用的代码 - 而web.config看起来像这样：
You almost certainly need authorization as well: almost no email systems these days are configured to allow "anonymous users" to send emails.
Have a look at this: Sending an Email in C# with or without attachments: generic routine.[^] - I know it works, because it's the code I use - and the web.config looks like this:
<appSettings>
<add key="Development" value="True"/>
<add key="SMTPHost" value="smtp.REDACTED.com"/>
<add key="SMTPCredentialUser" value="MyEmail@REDACTED.com"/>
<add key="SMTPCredentialPassword" value="MyPassword"/>
<add key="SMTPDefaultFromAddress" value="Webmaster@REDACTED.com"/>
</appSettings>
你能不能请确保您输入了正确的凭据？本地主机？这是正确的吗？
Could you please make sure that you have entered correct credentials? Localhost? Is it correct?
