JIRA sends mails for own actions

When I write a comment here, edit a comment or generally do anything here that triggers mail (and also creating reports) sends a mail to myself. But I know what I wrote! And I know that I wrote it! Other services (forums, wikis, networks, ...) don't send notifications for own actions.
I could maybe understand it if I could just answer the mail without opening the page to write a comment, but afaik that's not possible.
