This software is powerful. OE offers more options and features. Moreover, it is fast, though it was not tested to see if it was faster than Eudora. It is multi-threaded. It downloads messages and sorts them quickly.
Some additions are neat.
Hotmail support was added. Now you can handle your Hotmail account from OE 5.0 just as if it was a POP3 account. This is useful for someone who wants to have both the Web and a client to use e-mail. During testing, receiving and sending mail through the account worked as well as with a normal POP account, though checking requires a few more operations for OE to handle. When you use your Hotmail account, an icon will be added in your folder list to access your downloaded mail.
