    From what you've pasted, it looks like the culpret is MailScanner.

    I'd probably look into doing a couple things here:

    1. Make sure your mailscanner is up to date ( and whatever program you use for virus definitions, etc. )

    2. Look into further tweaking the mailscanner configuration.

    3. If the above fails, you might want to look into replacing mailscanner with ExiScan which is already built into cPanel's exim install. ( Search the forums for an installer, or use the one available to you under the addon modules in WHM > "cPanel" heading ).

    It's the latest mailscanner.

    anyway to flush out that 100MB big mailnulll?
    also TRACE OUT the domain that caused this.

    Have you looked into tweaking the config file? You can probably clear its current resources by killing off mailscanner and restarting it ( as well as exim ). But i'd really suggest you eather 1. tweak the config or 2. move onto exiscan

    There are mail stuck in the server. 100MB big. Removing this 100MB big file will definitely fix the problem. But i have no ideas how.

    Log into WHM and click on "manage mail queue" you will be presented with the email queue on your server with the size of each listed. You will also be given options to remove or send those messages.

    3-4 instances of this mailnull (100MB big) are hooking up alot of resources on the server.
    I am really desperate now. Can someone help or direct me to someone who is REAL GOOD in fixing this problem?
