Gmail IMAP 限制？答案

【问题标题】：Gmail IMAP Throttling?Gmail IMAP 限制？
【发布时间】：2015-08-23 13:51:47
【问题描述】：

我们的应用程序需要从 Gmail Sent 文件夹中获取电子邮件主题、发件人、收件人等。它工作了几个月，但它突然开始起作用。我们正在使用 AE.Net.Mail 来创建 ImapClient

new ImapClient("imap.gmail.com", "不适用", () => GmailSaslRequestBuilder.Build(email, this._authenticator.GetAccessToken()), ImapClient.AuthMethods.XOAUTH2, 993, 真）；

这是我收到的错误消息，我想知道我们是否受到限制以及如何解决这个问题或者还有什么问题？

【问题讨论】：

套接字被强制关闭，并且充满了名为“Authenticate”的例程的跟踪将使我的第一个猜测是身份验证失败。你为什么怀疑节流？

由于我没有 50 分的东西，所以我无法对您的问题发表评论，所以我会将我的评论写在答案表格中，您可以在下面发表评论。

无论如何，错误“System.Net.Sockets.SocketException：现有连接被远程主机强制关闭”的开始通常是由服务器上的 MX 设置引起的。我将首先检查您的 MX 记录验证。

但如果这不是问题，请在下面发表评论，然后我可以发表评论。
