离线IMAPS和CA证书

Question

这个问题是关于离线地图的，但在给定的机会下，我想要资源来了解更多关于 ssl 证书以及与它们的整个交易。

我下载了最新的离线地图 (7.0.6)，在完成最小配置后，我运行命令，但出现以下错误：

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 帐户下载所有邮件，然后弄清楚如何用 mutt 阅读它。但首先我想做的就是有一个文件夹，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

在不久之后的某个时候，offlineimap 开始验证 SSL 证书（是的，以前显然没有）。与其做明智的事情，并默认使用默认的系统信任存储，您需要手动配置每个远程存储库以指向证书列表。在 Debian/Ubuntu 系统上， 中的以下设置Repository GmailRemote应该可以解决问题：

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

在其他系统上，该文件可能位于不同的位置；网络搜索应该可以找到有关保存信任库的位置的详细信息。
