Re: folders in folders

For whatever it's worth, under 2.4.1, my subfolders are the same as always. Old subfolders still work. I can make new subfolders and they work too. When I look at my file system, the folders are like ".folder" and ".folder.subfolder", the same as always, even new subfolders.

So I think that is good news; it means it can be fixed, whatever is wrong. Perhaps the problem is kmail, and kmail doesn't understand that a folder of ".folder.subfolder" should be interpreted as, "subfolder" is under "folder"?

Hello,
after upgrade of the dovecot to 2.4.1 version my folders in folders
stopped working.
For example I had folder work and subfolder done. When accessing folder
work everything is working, but after accessing inner folder done, I get
error in kmail:
A000210 NO Character not allowed in mailbox name: '.' ( 0.001 + 0.000 secs
) . [ CANNOT ]
When I look into disk structure on disk, the folder name is .work.done. It
seems new version of dovecot does not allow the . in the name. How could I
fix this?
Thanks
Marek
