Popcorn is a lightweight POP/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 a POP3 server directly without downloading it to a local mailbox, making it ideally suited for roaming mail access, and for scanning, reading and sending mail over slow internet connections.
