Send Attachments From Finder via Folder Actions
This hint allows you to drag files to a Finder folder and have them instantly emailed to a pre-configured address, simply by attaching a Folder Action to the folder. It’s a great way to get files off your Desktop and backed up offsite.
Great tip from Mac OS X Hints in 2007 worth a re-link. I use this for Gmail every day, as there’s no better and faster way to get files off your Mac and onto Gmail.
