The log file is `extensions/MailPush/log.txt` on your kindle. Connect your kindle to computer and find it.
If you have set the `config.json` correctly, please check the following items：
- According to your mail service settings, enable IMAP service support on the settings page. The methods for different mail service may vary. For example, outlook enables IMAP service by default, so further operations are not required;
- In addition, some mail services (such as Yahoo, Google, mail. Ru) may generate an application password. Using your logging password may fail, so an error will occur and the download will fail.
By the way, I find that the machine translation from
