The mail contains an archive which amavis tries to unzip
While doing this, amavis exceeds the limits imposed by one of those
(MAX_EXPANSION_QUOTA I'd guess)

$MAXLEVELS = 30;
$MAXFILES = 6000;
$MIN_EXPANSION_QUOTA =      100*1024;  # bytes  (default undef, not enforced)
$MAX_EXPANSION_QUOTA = 200*1024*1024;  # bytes  (default undef, not enforced)
