OfflineIMAPS和CA证书

Question

这个问题是关于离线映射的，但是在给定的机会下，我想了解更多关于ssl证书及其处理的资源。

我下载了最新的offlineimaps (7.0.6)，在完成最小配置之后，我运行该命令，得到以下错误：

Account sync Gmail:
 *** Processing account Gmail
 Establishing connection to imaps://imap.gmail.com:993 (GmailRemote)
 ERROR: No CA certificates and no server fingerprints configured.  You must configure at least something, otherwise having SSL helps nothing.
 *** Finished account 'Gmail' in 0:00
ERROR: Exceptions occurred during the run!
ERROR: No CA certificates and no server fingerprints configured.  You must configure at least something, otherwise having SSL helps nothing.

Traceback:

    "having SSL helps nothing.", OfflineImapError.ERROR.REPO)

我想从我的gmail帐户下载所有的邮件，然后想出如何与mutt一起阅读它。但首先，我想要做的是有一个文件夹，里面有我所有的邮件。

这是我的.offlineimaprc

[general]
accounts = Gmail

[Account Gmail]
localrepository = GmailLocal
remoterepository = GmailRemote
ssl = yes
synclabels = yes

[Repository GmailLocal]
type = Maildir
localfolders = ~/Mail/Gmail

[Repository GmailRemote]
type = IMAP
remotehost = imaps://imap.gmail.com
remoteuser = [MY_E-MAIL]@gmail.com

在不太遥远的过去的某个时候，offlineimap开始验证SSL证书(是的，显然不是以前)。您需要手动配置每个远程存储库，以指向证书列表，而不是做明智的事情，默认使用默认的系统信任存储库。在Debian/Ubuntu系统上，Repository GmailRemote中的以下设置应该可以做到这一点：

sslcacertfile = /etc/ssl/certs/ca-certificates.crt

在其他系统上，文件可能位于不同的位置；web搜索应该找到有关信任存储的详细信息。
