我在Ubuntu 16.04.2 lts上运行的单声道(版本4.2.1(代码;该代码的尝试和未能使用Amazon SES发送电子邮件。从其他搜索中，我读到该错误是由于单声道信托商店中未存在证书引起的。解决此问题的命令：mozroots-import-ask-remove
接下来是：
certmgr -ssl smtps：//email-smtp.eu-west-1.amazonaws.com：587
(由于email-smtp.eu-west-1.amazonaws.com是我正在使用的SMTP服务器；在端口587上(
第一个命令正常工作，并将162张证书导入我的商店。第二个命令失败，例外。我究竟做错了什么？
这是堆栈跟踪：

certmgr的常见故障之一是没有使用sudo运行它。它产生了Exception，这是一个真正的误导。
在MacOS/Linux上：
certmgr -ssl smtps://email-smtp.eu-west-1.amazonaws.com:587
将产生您发布的确切错误。
使用sudo：
sudo certmgr -ssl smtps://email-smtp.eu-west-1.amazonaws.com:587
导致：
