A clamav-milter setup consists of the following three components:

* the clamav-milter itself

  --> this is provided by the 'clamav-milter' package plus (alternatively)
      'clamav-milter-upstart' or 'clamav-milter-sysvinit'

  The main configuration is in /etc/mail/clamav-milter.conf and MUST
  be changed before first use.

  The -sysvinit package is managed by the traditional tools, but
  -upstart requires modification of /etc/event.d/clamav-milter to
  enable automatic startup.  See comments there for more details.

* a clamav scanner daemon

  --> this package is called 'clamav-scanner' plus (alternatively)
      'clamav-scanner-upstart' or 'clamav-scanner-sysvinit'

  The daemon is configured by /etc/clamd.d/scan.conf (which MUST be
  edited before first use).

  The -sysvinit package is managed by the traditional tools, but
  -upstart requires modification of /etc/event.d/clamd.scan to enable
  automatic startup.  See comments there for more details.

* the MTA (sendmail/postfix)

  --> you should know how to install this...

  When communicating across unix sockets with the clamav-milter, it is
  suggested to use the /var/run/clamav-milter/clamav.sock path.  You
  have to add something like

    INPUT_MAIL_FILTER(`clamav', `S=local:/var/run/clamav-milter/clamav.sock, F=, T=S:4m;R:4m')dnl

  to your sendmail.mc.



It is suggested that components communicate through TCP sockets as
this eases setup.  Please add corresponding packet filter rules!
