There was a Mail Launcher application but the official website doesn't contain any information about it. The official website hosts a blog without posts or anything to indicate something related to spam fighting.

If you use an online service, then you will have to configure the client to reject the mails you don't need because most of the services already have a Spam filter installed to avoid spam mails.
