Upgrading MailScanner and ClamAV

Upgrading MailScanner

• Remove any previous versions before downloading:
  rm -fv msinstall.tar.gz
  rm -Rfv msinstall/
  
  
• Run the following commands from the root shell:
  wget http://www.configserver.com/free/msinstall.tar.gz
  tar -xzf msinstall.tar.gz
  cd msinstall/
  sh install.sh
  
  Select option 1 to upgrade
• Check that MailScanner has restarted OK:
  tail -f /var/log/maillog

Upgrading ClamAV

• Download the latest stable ClamAV distribution from http://www.clamav.net
• Expand the distribution and cd into the resultant directory and build ClamAV using:
  tar -xzf clamav-*
  cd clamav*
  ./configure --disable-zlib-vcheck
  make
  make install
  replace "Example" "#Example" -- /usr/local/etc/freshclam.conf
  replace "Example" "#Example" -- /usr/local/etc/clamd.conf
• Run freshclam to download the latest definitions:
  freshclam
  
• If you're using the clamavmodule, check you have the latest version installed:
  /scripts/perlinstaller --force Mail::ClamAV
• Then restart MailScanner with:
  service MailScanner restart

That's it. If you don't feel confident doing any of this yourself, or if you get into a horrible mess, we offer a cheap package to do it all for you, and more, over here.

*Remember that adding virus scanning of emails to MailScanner will add load to your server.
