I am having subtle problems with IMAP mailbox configuration on certain clients such as KMail and Thunderbird, whereas the previous setup was working on K9Mail (mobile) and Trojitá (desktop).
I was using Maildir folders, which were mostly working before, but for some reason I had to create explicitly named namespaces for the flatfile (mbox) Inbox and the Maildir "Home" folders. I also specified an INDEX directory for the inboxes, which I made world-writable and sticky, because of permission problems creating subdirectories in it.
KMail always seems to put sent mail into a local "sent-mail" folder, rather than the IMAP Sent folder associated with the sending account. (KMail and Thunderbird have a more POP-oriented architecture for the desktop, whereas Trojitá is exclusively IMAP.)
Is there an easier better way to organize some of this stuff? Or how is it "usually" done?
