    2 weeks ago i replaced my ispconfig server.

    So i installed an new server folowing:

    http://www.howtoforge.com/perfect-server-ubuntu8.04-lts

    And after that i backuped and restored the ispconfig database. After that i had to modify some custom files and all is ok.

    But now i have a problem with reading email from squirrelmail. All reading is ok but when i open mij inbox (4000 messages) IMAPD hits 100& cpu.

    So i started to trace the pid op imapd
    strace -p 17222

    And it seems that courier reads al files in the cur directory every time i open the inbox in squirrel. I didn`t see this issue using my old server.

    What is wrong with courier ?

    In the user.pref file of squirrel there was a option

    sort=0

    this option slowed down the index, because it will sort all mail in the inbox folder, not sure wich plugin set this option....

    No placed:

    #sort=0 and the problem is solved...
