Mail client hell

I upgraded my machine at work on Tuesday to windows XP professional. I have finally gotten all the programs I need to survive. We use Eudora here as our corporate E-Mail client. When I was still running Win98 I used Outlook express for my personal mail. When I upgraded the OS I also upgraded Outlook and let me tell you it sucked. I know it sucked before but now it really sucks.

I use IMAP so I can have all the same folders no matter where I set up shop. I also have all my sent mail in one place if I need it. Now Outlook won’t let me set the remote folder as my sent folder. and there are many other problems I won’t even mention.

So my question to you who read here other then Eudora and the Outlook family what else is out there that is good and robust.
