I don't know how to import to Evolution, but this is the way to get the EXACT copy of thunderbird in linux.
1. Install Thunderbird
yum -c "yum install thunderbird"
2. Mount windows file system (in should be preinstalled and mounted at boot automaticly, but just in case it isn't):
2.1 . Install NTFS driver:
sudo -c "yum install ntfs-3g
2.2. Locate your NTFS drives:
su -c "/sbin/fdisk -l"
Look the system column for NTFS and remember it's device
2.3. To mount on boot do this for each NTFS device you have:
su -c "mkdir /media/#display_name# #use any you want.
su -c "echo -e '#device_name# /media/#display_name# ntfs defaults 0 0 \n' >> /etc/fstab"
2.4. Restart X (Ctrl+Alt+Backspace) or restart computer or just run
3. Open your partition where your windows is installed (usually C:) in linux.
Copy all from Documents and Settings/#your_win_username#/Application Data/Thunderbird to ~/.thunderbird (~ stands for home in linux - /home/#your_linux_username#)
But now when you're running 2 mail clients: if you're using POP, POP will erase a massage from the server when it's downloaded. So mails you have downloaded in windows, won't be avaible in linux. You should use IMAP, if is your mail server support it. If not, you can make script in /etc/ rc3.d folder to import files from the windows when booted and export files when being shuted down..
