Automatically Recognize Email Domains

[GXY2017]

Very good plugin. Could it be improved further?

1. Is it possible to automatically recognize the email domain?
2. Some domains come from the same issuer but may have different names, such as @service.jpm.com and @account.jpm.com. In this case, they should also be considered the same sender.

The reset rules button / initial startup should already auto detect domains
