OT: CrossPlatform email client?

[Bryan Anderson]

Hi - this seems a fairly newbie friendly place and I got a lot
of good help from some people here with my mp3 problem, so maybe
someone will have an answer to this one....

I really, really want to me rid of MS......but there are a few
things that I need to dual-boot for, for a while. I *know* that
the Gimp is supposed to be as good as many Windows graphics
packages but I know the Windows ones inside out and use my PC
to make money. Ditto for Dreamweaver.

Because of these two apps (mainly) I find that I spend most of
the day in Windows and then the evening in Linux (mostly email,
usenet, etc). However I am getting fed up of trying to organise
email in a dual-boot system. Receiving email into either is
easy enough (just leave on the server in Linux, delete from
server in Win) but if I then reply to something when in one OS,
my reply won't appear in the second, etc.

Is there a (decent) email client that works with a shared mail
dir, on a fat32 drive, and has a Windows and a Linux client. It
needs:

to be easy to set up/install (complete newbie!)
multiple account facilities (both pop and smtp)
decent filtering, rules and folders setup

Basically I'm after The Bat! or maybe Eudora, that will work
for both OS's......
