Short description of Autosend 3.0: Share files with your friends or with the entire world by email. Easy and safe ! Like a filesharing server (plenty of features) but through your regular email client. Emails are easy to use, can go through firewalls. Accessible to everybody everywhere...
Just configure a server with its own email address and people can ask you a file just by sending an email which subject is the filename of the desired file. The file is sent back as attachment.
