           Summary: KMail reports incorrect IMAP folder size

          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: rodney.baker optusnet com au

Running KMail with a dovecot IMAP server and using Maildir for mail storage. KMail talks to the IMAP server both locally and across a LAN.

The folder sizes reported in the folder list appear to bear no relationship to the actual size stored in the maildir. Two different machines (one local, one on the LAN) report different folder sizes for the same folders. The folder sizes increase when new messages are received and do not decrease when messages are deleted/expunged.

For example, my desktop machine reports the inbox size as being 917kB but the laptop reports only 6.5kB. I use the desktop machine much more than the laptop so KMail has opened a lot more mail there than on the laptop. The folder size appears related to the amount of mail actually read by KMail rather than the size of the folder in the mail store.
