Windows XAMPP捕获一个本地邮箱或文件夹中的所有PHP mail（）

Using XAMPP on Windows I am developing a WordPress site and need to catch all outgoing emails into a single local mailbox or even a folder. I am testing a plugin that sends out emails, it would be easier to do this locally rather than updating the remote Linux server on every small change.

Any advice on the simplest way to do this?
