Description Martin Scharrer 2006-12-06 14:01:51 UTC

Version:            (using KDE KDE 3.5.5)
Installed from:    Gentoo Packages
Compiler:          gcc (GCC) 4.1.1 (Gentoo 4.1.1-r3) 
OS:                Linux

When I make a mbox file in ~/Mail read-only KMail brings
a KNotify warning window:

Cannot open file "/home/<user>/Mail/<mbox name>":
Permission denied

It seems that KMail is only trying to open the mbox read-write and has no read-only fallback.

I see this as a bug because it doesn't allow for 'archive' mbox files which should be still read- and searchable by KMail but should not be changed any more.
Also a selectable property 'read-only' for the mbox in KMail would be a wishable feature.

NOTE: This worked in a older version of KMail (ca. 3 Years ago), also e.g. symlinking a mbox to a CD or other ro memory: 
mbox -> /media/cd/mbox 
worked very well.

Confirmed in KDE 4.3. But I think kmail relies on the writing ability for changing the status of message i.e.

Fix handling of read-only mbox files

Up till now a read-only mbox file could not be loaded, since load()
always tried to open in read-write mode.
Now it first tries to open the file readWrite and if that fails,
it retries readOnly.
Also one can now explicitely tell the class to open the file readOnly
even if it could be written.
