I've tried quite a few email apps and am currently running Eudora on my wife's machine. A long time ago on my machines, I decided Eudora just didn't cut it anymore. Outlook express is out since I opt for non ms applications whenever possible and I think spammers target OE in particular. I went with Mozilla and even use the mailer included. The latest version is 1.7b and the mailer has filters that beat any I've tried. Besides, I prefer the browser over IE. I have five email addresses. For serious stuff on one, I block everything except for addresses that are already IN my address book. On the other addresses, I filter to suit the use. My wife's machine with Eudora, OE and the same email addresses is constantly bugged with spam, but Mozilla's mail app seldom gets a spam email. It does take a some trouble setting up and getting used to Mozilla, but seems to be worth it. Installation is really easy, just dump it into a directory and it will pick up all IE's bookmarks. When a new beta version comes up just delete the directory and the new version will still get all the old settings. And its for free.
(Your ISP probably has filters too. One of my ISPs is pretty good at blocking spam before It gets to me and the other one is absolutely great at it. I have run a web site for years and can't remember when I've received spam at the address I use there.)
