As a long time used of KDE and Kmail I was surprised to find so much trouble in setting up under KMail2. One real problem was that I could not find any handler for the traditional UNIX spooled mail. I had to change the system configuration to deliver mail through procmail (I haven't had to use that in at least a decade) into a user based maildir and hand off the maildir to KMail2. Once there it appears that there are no options for filtering - I suspect that the devels thought that all of the mail filtering and such would be done in procmail, but I find the single maintenance point and GUI in KMail a lot handier.

After changing postfix I now have 2 maildirs and one pop3 account. One of the maildirs is the incoming mail that hasn't been filtered and I'd like to have KMail apply it's filters and distribute mail. I've been doing it manually but that loses messages, I'd really like KMail to do it (and maybe not lose messages?). I don't want to maintain filtering in both procmail and KMail.

Qt: 4.8.0
KDE Development Platform: 4.8.1 (4.8.1)
KMail: 4.8.0

As far as I know, there are a number of issues open with filters. I run git master, so I'm not sure if any fixes appeared in stable branches.
BTW, Kmail can handle UNIX mailboxes just fine.

In the Kontact Configure->Accounts->Receiving->Add all I can find are IMAP, KMail Mail Folder, Pop3, MailDir, and MBox (is that last new to 4.8.1?). None implement fcntl locking which I thought was the /var/spool/mail locking method nor do any suggest a mail spool path.

One other question: is there any documentation on account and folder properties? The one I'm particularly interested in is the meaning of "Act on new/unread mail in this folder". What activity does that affect?

On edit: never mind, found what I needed in the online docs. Now I'm trying to figure out why messages have become zombies - delete them and they return. Only way I can kill them for good is to move them to a particular folder and delete them from the file system.

You may want to file a wishlist report for mail sppols on bugs.kde.org. I haven't used this feature in a long time (I used to around KDE 3.3) so I'm not sure if it was properly ported or not.
