本人使用邮箱zz****@outlook.com购买了markeditor，出现了3个问题需要咨询下：

1 – 邮箱未收到License邮件，垃圾邮件也查看了，没有收到；

2 – 使用该邮箱地址注册的时候出现以下错误

Signature Version 3 requests are deprecated from March 1, 2021. From that date on, we are progressively rejecting such requests. To resolve the issue you must migrate to Signature Version 4. If you are self-signing your requests, refer to the documentation for Authenticating requests to the Amazon SES API [1] with Signature Version 4 [2]. If you are not self-signing your requests, simply update your SDK/CLI to the latest version.

3 – 如何绑定bitcron到自己的网站，有没有说明文档提供。

谢谢！
