我正在尝试配置offlineimap以下载我的gmail，但出现错误：
OfflineIMAP 6.5.7
Licensed under the GNU GPL v2 or any later version (with an OpenSSL exception)
Account sync Gmail:
*** Processing account Gmail
Establishing connection to imap.gmail.com:993
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!

我的.offlineimaprc是：
[general]
accounts = Gmail
maxsyncaccounts = 3
sslcacertfile = /etc/ssl/certs/ca-certificates.crt
[Account Gmail]
localrepository = Local
remoterepository = Remote
[Repository Local]
type = Maildir
localfolders = ~/mail
[Repository Remote]
type = IMAP
remotehost = imap.gmail.com
remoteuser = wdrnls@gmail.com
remotepass = Secret
ssl = yes
maxconnections = 3
realdelete = no
我指定我的证书在哪里。为什么仍会出错？
