It's really quite simple if you don't already get it.

%Size is a hash. It is not a reference. You might declare it like so

my %Size = ( foo => 'bar', baz => 'qux' );

$Size is not a hash. It might be a SCALAR, it might be a reference,
perhaps to a HASH. You might declare it like so:

my $Size = { foo => 'bar', baz => 'qux' };

or

my $Size = \%Size; # a direct reference to %Size

or

my $Size = {%Size} # a reference to a copy of %Size

Since process(0 expects a HASH reference, you can't just pass it %Size
directly, you have to pass a reference or a copy:

$sut->process($filename, \%Size, \$msgbody) or die $sut->error;

However, if $Size really is a HASH reference, then you just pass it 'as is'

$sut->process($filename, $Size, \$msgbody) or die $sut->error;

See http://perlmonks.com/index.pl?node_id=69927&displaytype=print for
a great reference on this stuff.
