    I have installed the Mailscanner option on the CPanel downloads (Latest MailScanner installer [exim4 virus scanner] (unsupported):
    mailscanner-autoinstall-1.5.tar.gz (Sat Aug 2 21:53:19 2003))

    Recently, I see very high cpu states with the Clamscan process (sometimes 50%, which results in loads higher than 5 - 6)

    Is it normal that the Clamscan process takes that much? Is there a way to lessen this (besides uninstalling :))?

    Thanks.

    Try upgrading to the latest mailscanner and using clamavmodule instead of clamav. That should reduce the load. It did for me.

    upgraded to the latest and ran the perl module and ive found that all is ok then suddenly loads go thru the roof and the only fix is to killall -9 mailscanner and then restart mailscanner

    anyone else found this or know of a solution???

    Im running this on a hyperthreaded 3Ghz P4 with 2Gb ram so it should never have become an issue

    Go on, have a guess
    Just to check, did you do all the following steps:

    You installed Mail::ClamAV:

    /scripts/perlinstaller Mail::ClamAV

    You then edited your /usr/mailscanner/etc/MailScanner.conf file and changed the line:

    Virus Scanners = clamav

    to:

    Virus Scanners = clamavmodule

    Then killed off all the MailScanner processes and restarted MailScanner?

    Doing this should work, as it has for me on many servers and many others here.

    I had the same problem. Only reinstalling with the autoinstaller and with these :


    This is a revised howto from the one posted by anand at the cPanel forums.
    http://forums.cpanel.net/showthread.php?s=...ighlight=clamav

    If you already have MailScanner installed:
    1) cd mailscanner-autoinstall-1.5
    2) ./uninstall

    If not, start here:
    1) Install the following perl modules from WHM:
    Net::CIDR
    Inline
    2) wget http://layer1.cpanel.net/mailscanner-autoi...tall-1.5.tar.gz
    3) tar -xzvf mailscanner-autoinstall-1.5.tar.gz
    4) cd mailscanner-autoinstall-1.5
    5) wget http://www.sng.ecs.soton.ac.uk/mailscanner...4.28.6-1.tar.gz
    6) mv MailScanner-4.28.6-1.tar.gz MailScanner-4.28.6.tar.gz
    7) pico install
    8) Change QUOTE
    $version = "4.22-5";
    to QUOTE
    $version = "4.28.6";

    9) ctrl-x to save
    10) wget http://twtelecom.dl.sourceforge.net/source...-0.70-rc.tar.gz
    11) pico claminstall
    12) Go to line 10, and replace tar xfzv clamav-0.60.tar.gz with tar xfzv clamav-0.70-rc.tar.gz
    On line 11, replace cd clamav-0.60 with cd clamav-0.70-rc
    13) ctrl-x to save


    directions (from http://forum.cpanelhosts.com/index.php?act=ST&f=2&t=299&st=0)



    and than manually (not through whm) installing mail::clamav did it. But now I get a lot of defuncts and hanging mailscanner processes, so I shut it down to avoid enormous loads.

    I've deinstalled mailscanner. I'm sick of the loads and Mail::ClamAv doens't seem to work (the virus warnings suddenly stopped as where I received a couple in an hour before.

    Does anyone know of another scanner, which doesn't take so much load???

    Another idea would be to use clamdscan instead, since libclamav is a bit recent

    I'm not 100% sure on how to do this yet, I'll have to post a thread on the mailscanner forum/mailing list
    if anyone beats me there, please post a pointer here...

    An extract from clamav website

    http://clamav.sourceforge.net/doc/0.70/html/node19.html

    Clamdscan

    it can't use external unpackers


    So what happens to attachment scanning ?

    hmmm...

    Another extract from clam website

    All ClamAV scanners depend on LibClamAV. It has a built-in support for the following formats:
    Zip
    Gzip
    Bzip2
    RAR (2.0 only)


    Probably answer to my own question :p

    I experimented with the versions of Mail::ClamAV and Mailscanner.

    I used the lastest version of Mailscanner and 0.6 of Mail::ClamAV.

    After that I only had to install one more Perl module and the thing worked.

    Well i know about that thread, and if you look at the last few posts in which you say you had trouble with Inline module and reinstall it, you will find that there is no posting on what module needs to be installed additionally to solve it.

    Probably i wud have missed it, thats the reason i posted the message asking you which module was it. anyways...
