我的目标是从 Gmail 帐户同步我的电子邮件并将它们编入索引以在 Emacs 中搜索和阅读。后者尚不相关，因为我无法将电子邮件同步到我的笔记本电脑。

我正在运行 Mavericks，因此在 Mac Terminal 中工作。

我已经按照SO 接受的答案和试图使用offlineimap的同一线程中的答案，以及本（更有希望）教程中关于使用isync（以及mbsync）的第二种方法。两种方式最终都使用mu和 Emacs 的接口：mu4e。

未正确读取/解释证书。我不知道为什么，因为我不明白错误消息。这是来自offlineimap的一个：

这是来自mbsync的：

> C: 0/3  B: 0/2  M: +0/0 *0/0 #0/0  S: +0/0 *0/0 #0/0
Error while loading certificate file '/usr/local/etc/openssl/certs/Equifax.crt': error:00000000:lib(0):func(0):reason(0)
C: 3/3  B: 0/2  M: +0/0 *0/0 #0/0  S: +0/0 *0/0 #0/0

我已经用 Homebrew 安装了所有东西，并按照教程使用文件夹。问题来自证书，但我不知道问题可能是什么。我在 Gmail 中设置了允许 IMAP 并允许连接不太安全的应用程序。

我如何以不同的方式处理证书？

对于offlineimap 错误，谷歌抱怨你没有使用Oauth2。按照这里的解释，我解决了同样的offlineimap问题：https ://github.com/OfflineIMAP/offlineimap/issues/228

您需要将您的配置.offlineimaprc为使用 Oauth2 而不是指定用户名/密码。以下是有关如何生成令牌的模板和说明： https ://github.com/OfflineIMAP/offlineimap/blob/master/offlineimap.conf#L764

这是重要的设置：

auth_mechanisms = GSSAPI, CRAM-MD5, XOAUTH2, PLAIN, LOGIN
oauth2_client_secret = ...
oauth2_client_id = ...
oauth2_refresh_token = ...
