Mail help needed . . .

[Ronn! Blankenship]

Since after 10+ years of my using them both Netscape and Eudora are 
going away, I am at the point where I have to change both browser and 
mail programs.  I spent past several hours yesterday installing 
Mozilla Firefox and Thunderbird and trying to import stuff from the 
old programs.  Firefox may be a satisfactory browser but I am quite 
disappointed in the lack of functionality of Thunderbird as a mail 
client compared with Eudora, so I thought I'd ask if anyone has any 
(obviously, non-M$) recommendations?


TIA,
