GNU Emacs Gnus无法连接到gmail IMAP

Question

我正在配置Gnus以通过IMAP从我的gmail帐户中检索电子邮件。我已经按照https://www.emacswiki.org/emacs/GnusGmail的建议做了，但是在启动时我一直在从Gnus那里获取错误：

我已经安装了GnuTLS，gnutls似乎与imap.gmail.com:993一起工作，我正在“准备好Gimap以满足请求”。

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……看起来是这样的：

machine imap.gmail.com login mark@mydomain.com password my_password port 993
machine smtp.gmail.com login mark@mydomain.com password my_password port 587

有什么问题吗？

Gmail默认不允许从不符合其模糊定义的安全标准的客户端访问IMAP --我遇到了与用Python的imaplib编写的脚本相同的测试。您需要访问该网站，并启用从不太安全的应用程序连接。
