使用 Google Apps 电子邮件/smtp 从网站发送邮件时出现问题

发布于 2024-11-14 08:43:26 字数 1193 浏览 4 评论 0原文

我有一个 Asp.Net 网站，它使用 google SMTP 发送电子邮件。使用以下配置，它可以与正常的 gmail 帐户一起正常工作。

<smtp from="[email protected]">
<network host="smtp.gmail.com" port="587" userName="[email protected]" password="mypassword" enableSsl="true" /></smtp>

现在我需要使用 Google Apps 电子邮件和 smtp，我尝试更改配置，如下所示，

<smtp from="[email protected]">
    <network host="smtp.gmail.com" port="587" userName="[email protected]" password="mypassword" enableSsl="true" /> </smtp>

但它抛出身份验证失败错误！！！
“SMTP 服务器需要安全连接，或者客户端未经过身份验证。服务器响应是：5.5.1 需要身份验证。了解更多信息”

我仔细检查了 Google 电子邮件设置、用户名和密码，但仍然无法解决问题！

关于这个问题的任何想法都会有很大的帮助。

谢谢和问候，
安兹

I have an Asp.Net site which uses google SMTP to send emails.. its working fine with normal gmail accounts using the below configuration

<smtp from="[email protected]">
<network host="smtp.gmail.com" port="587" userName="[email protected]" password="mypassword" enableSsl="true" /></smtp>

Now I need to use Google Apps email and smtp and I tried to change the configuration as shown below

<smtp from="[email protected]">
    <network host="smtp.gmail.com" port="587" userName="[email protected]" password="mypassword" enableSsl="true" /> </smtp>

But its throwing the Authentication failed error!!!
"The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at"

I double checked the Google EMail Settings, Username and password but still couldn't solve it!!

Any thoughts on the issue will be a great help..

Thanks and Regards,
Anz

来自 MSDN：

某些 SMTP 服务器要求
客户端在之前进行身份验证
服务器代表它发送电子邮件。放
当此属性为 true 时
SmtpClient 对象应该进行身份验证
使用默认凭据
当前登录的用户。如果
UseDefaultCredentials 属性已设置
为 false，则在中设置的值
凭证属性将用于
连接到时的凭据
服务器。

    client.UseDefaultCredentials = false;
    smtp.EnableSsl = true;
    client.Credentials = new System.Net.NetworkCredential(username, password);
    ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; }; 

    smtp.Send(mail);

From MSDN :

Some SMTP servers require that the
client be authenticated before the
server sends e-mail on its behalf. Set
this property to true when this
SmtpClient object should authenticate
using the default credentials of the
currently logged on user. If the
UseDefaultCredentials property is set
to false, then the value set in the
Credentials property will be used for
the credentials when connecting to the
server.

    client.UseDefaultCredentials = false;
    smtp.EnableSsl = true;
    client.Credentials = new System.Net.NetworkCredential(username, password);
    ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; }; 

    smtp.Send(mail);
