Amavisd-new+Exim3 trouble

["Martin" <cia@vf.cz>]

Hello,
i have problem with Amavisd-new (uses Spamassassin 2.63 and
ClamAV 0.67) in only positive spam scenario...
the mail is correctly quarantined but Exim generates an
following error response to the spam sender:


 This message was created automatically by mail delivery
software (Exim).

 A message that you sent could not be delivered to one or more
of its
 recipients. This is a permanent error. The following
address(es) failed:

   user@destination.domain
     Child process of amavis transport returned 69 (could mean
service or program unavailable) from command:
     /usr/sbin/amavis



Did anybody knows what this mean or have any idea to correct
this?

Thanx and excuse my ..ehm.. horrorible english

Martin
