Jon et al, I'm not sure what kind of capabilities you're looking for in an email client, but Thunderbird (being open source) has a number of extensions available. If you're ambitious and creative, you can even write your own extensions. <a href="https://addons.mozilla.org/en-US/thunderbird/browse/type:1">https://addons.mozilla.org/en-US/thunderbird/browse/type:1</a> Disclaimers: Although I do use T-Bird for one mail account, I use it fairly generically. I know nothing of Eudora except what's been mentioned in this current thread. T-Bird's builtin spam filter leaves LOTS to be desired, but I have written several filter rules and that is very effective.  Other filters move messages into various folders, e.g. "newsletters", "bicycle", depending on subject or from line For most of my email, I use gmail and love it.

Duaine, I know you're an open source junkie but some things are best left the way they are. -- Regards, Jon Page </blockquote></div>
