GNU Emacs Gnus 无法连接到 gmail IMAP

我正在配置 Gnus 以通过 IMAP 从我的 Gmail 帐户检索电子邮件。我已经按照建议完成了https://www.emacswiki.org/emacs/GnusGmail，但是我在启动时不断收到来自 Gnus 的错误：

我安装了 GnuTLS，并且 gnutls-cli 似乎可以与 imap.gmail.com:993 配合使用，我收到“OK Gimap 已准备好请求”。

这是我的 ~/.gnus：

(setq gnus-select-method
      '(nnimap "gmail"
          (nnimap-address "imap.gmail.com")
          (nnimap-server-port 993)
          (nnimap-stream ssl)
          (nnir-search-engine imap)
          (nnimap-authinfo-file "~/.authinfo")))

(setq smtpmail-smtp-service 587
      gnus-ignored-newsgroups "^to\\.\\|^[0-9. ]+\\( \\|$\\)\\|^[\"]\"[#'()]")

我的 ~/.authinfo 看起来像这样：

machine imap.gmail.com login [email protected] password my_password port 993
machine smtp.gmail.com login [email protected] password my_password port 587

可能是什么问题呢？

默认情况下，Gmail 不允许不符合其模糊定义的安全标准的客户端访问 IMAP - 我在测试用 Python 的 imaplib 编写的一些脚本时遇到了同样的情况。您需要访问该网站并启用安全性较低的应用程序的连接。
