Popcorn is an ultra-lightweight POP3/SMTP e-mail client, free from unwanted and useless bloatware features. Being a true client/server application, it does not work in the same way as a typical mail program. This means that you're reading mail from the POP3 server directly, without downloading it to a local mailbox on your PC (although you can save mail messages locally if you want to). This makes it ideally suited for "on the road" mail access, and for scanning, reading and sending mail over slow Internet connections.
