通过 Calibre 将电子书从 Linux Mint 发送到 Kindle Paperwhite

Question

我正在尝试使用 Calibre 将一些电子书从我的 Linux Mint 桌面发送到我的 Kindle Paperwhite，但出现错误：

Starting job: Email Counter-Clock World to  me@free.kindle.com 

Sending failed...

Traceback (most recent call last):

Waiting 1 seconds before sending, to avoid being marked as spam.
You can control this delay via Preferences->Tweaks

使用以下设置通过 calibre 发送测试电子邮件： “发送电子邮件来自：” blah@blah.com（这个地址被我的亚马逊账户识别） “主机名：” smtp.gmail.com “端口：” 25 “用户名：” myemail@gmail.com “密码：”正确的密码 “加密：”SSL

得到了错误

Log:

在这里完全不知所措。有什么见解吗？

Answer 1

您似乎正在尝试使用 Gmail 帐户发送电子邮件。

据我了解，Google 不允许客户端通过端口 25（通常为未加密的 SMTP 保留）进行连接。

在他们关于第三方电子邮件客户端设置的Gmail Help article 中，他们指示使用端口 587 和 SSL 和 TLS（我不确定 Calibre 是否支持这些设置）。

除此之外，您还需要：

• 允许Less Secure Apps 访问您的 Google 帐户（如果您启用了 2 因素身份验证，这将不起作用）。

• 仅为 Calibre 创建一个 Application-specific password（这需要启用 2 因素身份验证）。
