Apologies. It seems that I forgot to switch on list management in kmail.
I've re-sent the message, this time to the list. It should arrive along with
this.
In kmail, are you using disconnected IMAP? A snippet from an email I sent
to the Alpine (email client) list: (the last two links are the most
interesting)
I've never seen kmail mentioned in a positive context. Its maildir
support is broken (doesn't follow the same naming rules as most
MTAs/MDAs for subfolders. Not a "real" standard, but it is a de facto
standard), and it eats IMAP mail. At the least, warn your correspondent
to stay away from kmail's "disconnected IMAP" feature:
