nPOP – added 7/24/2002
This email client allows you to access e-mail on a POP3 mail server on your Pocket PC or PC. It provides the function of common remote e-mail access. The mail displayed by nPOP is only the mail on the present on the server. Therefore, if mail is deleted from your server it will disappear from a list, even if the mail is displayed in the list. When you connect using nPOP, the mail is listed and you can see the header only. From that list you can select e-mail you want to receive on your Pocket PC or PC.

Ultrafunk Popcorn – added 3/18/2004
Popcorn is an ultra-lightweight POP3/SMTP e-mail client, that allows you to read mail from a POP3 server directly, without downloading it to a local mailbox on your PC (although you can save mail messages to disk if you want to). This makes it ideal for “on the road” email access, and for scanning, reading and sending mail over slow internet connections. (development has stopped, but last version is here)
