[Dovecot] IMAP client dependence on dovecot mail storage fromat?
Hi,
After setting up a maildir tree with :LAYOUT=fs and accessing it with KMail and Thunderbird, various mail client-specific problems appeared, but, as I didn't try with maildir++, I would like to confirm here: does that matter for an IMAP client much if I store mail on server as ":LAYOUT=fs" or maildir++? Can it see differences? I would like to think, that IMAP protocol should provide for all transactions in a standard way and its dovecot's/server's sole business how it stores mail locally. However... These results seem not very good: KMail: try creating a folder "sub" in "parrent" and you'll get "parrent.sub" along with "parrent" on server side. There, however, are no problems with Latvian unicode chars. Thunderbird: it can create a new folder in "parrent" as desired, but it can't display Latvian unicode chars (being such at server side) on client, while, if I try creating a new folder with Thunderbird with these chars, on server it will look somewhat like base64!
So I'm really confused. All together these things are pretty frustrating, sure, but I'd like to understand whats the real problem here!
It might be useful to add this conversation here:

On top of that, its impossible to create and access a new folder with KMail on my dovecot: it doesn't happen, that a new folder would be created with name "newfolder" into "parrentfolder", but along with the latter "parrentfolder.newfolder" is created!
Hmm. "parentfolder.newfolder" sounds like maildir++. All KMail (and also Thunderbird) does is tell the IMAP server to create a folder "newfolder" below the folder "parentfolder". It's up to dovecot to actually create the folder in its storage as needed. I cannot imagine why a folder created by Thunderbird results in parentfolder/newfolder while a folder created by KMail results in parentfolder.newfolder unless you switched dovecot's storage format. Well, that is weird to me as I didn't! No joke, I did again: Thunderbird 3.0; KMail 1.12.1 Using KDE 4.3.1 (KDE 4.3.1); dovecot-1.2.6; So:
- create folder TOP with KMail, then create a subfolder sub, which results in: "TOP" and "TOP.sub" (both prepared as maildirs with cur,new,tmp and maildirfolder file);
- create folder "TOP2" on the same fs level with Thunderbird, then create a subfolder "sub2" into it, which results in: "TOP2" prepared and containing "sub2" also prepared (prepared just like with KMail).
So... Its reality!
