Magic Mail Folder turns any folder on your desktop into an email-sending-box. You just have to give your freshly created folder(s) the name of an email address (like myFriend@hotmail.com) and it will be recognized.
Simply drag files in it and they will be sent.
MMF works as a daemon. Here’s a demo.
Please note that MMF is still in a beta-test stage. Please report any bugs. Thank you !
