QMAIL is a communications program which deserves to be more well known: it supports POP3, IMAP4, NNTP & RSS protocols.
Installation simply involves copying the files to the Pocket PC.

Besides IMAP4 support, it supports SSL/TLS authenication (which makes it compatible with GMail, but this requires a seperate download), filters and all the configuration options that you could imagine. HTML support is still not working for the Pocket PC. Neither is the ability to compose scripts.

To read a RSS feed, you only need to create an account and choose RSS in the "Class" menu. When you return to the main screen you choose the account that you just created, tap and hold to bring up "Create" and voila, after entering the name of the feed, you only have to give the URL. The interface is not bad: you click on the title to see the contents, providing quick access.

Installing QMail is not trivial, and since the original manual is in japanese, we have found a how-to to explain to you how to install QMail on your device here: http://www.modernnomads.info/wiki/index.php?page=Installing+and+configuring+QMail
