Changes to amavisd-new require amavisd-milter upgrade

[btisdall]

Users of amavisd-new should note that version 2.4.3 introduces v2 of the AM.PDP protocol which is NOT compatible with 1.1.x or lower versions of amavisd-milter.

If upgrading to amavisd-new 2.4.3 or higher (FC users note this will happen 'automatically' with 'yum upgrade') you'll need to download amavisd-milter 1.2.x from here:

http://sourceforge.net/projects/amavisd-milter/

And compile & install it as per the Amavisd howto, remembering to restart the milter when installation is complete.
