Version:           1.9.6 (enterprise 20070904.708012) (using 3.5.7 "release 72.6" , openSUSE 10.3)
Compiler:          Target: x86_64-suse-linux
OS:                Linux (x86_64) release 2.6.22.17-0.1-default

I recently upgraded from SuSE 9.3 to openSuSE 10.3 on two different computers.  I copied the Mail file from my old installation (renamed it old_Mail) to my new user account (I had to replace the disk), fired up kmail and used the Import feature in the File menu.  Not everything worked as I expected, but I ultimately got a working setup and access to all my old mail, all located in a Mail file in my home directory that I did not create.  However, in the meantime, I had set up kmail on another machine where the operating system upgrade occurred first, and had been receiving mail there .  When I went to that system to copy the Mail file over to the system I now had a running kmail on and import it suitably renamed, I could find no Mail file in my home directory.  Only after reading the bug reports did I see that there had been requests to hide the Mail file.  I did find it in .kde/share/apps/kmail, but this behavior is not consistent with what happened on the other machine, where no such file exists.  What is going on here?  What is the defaullt behavior on first invocation of kmail?  Use a Mail file if it exists?  Otherwise create a hidden mail file?  The Import documentation assumes a Mail file exists.  I didn't create one, but one existed after I imported.
