I'm not sure I understand the question (given monarch's response). Does it help if I say that param() returns multiple values in list context? That is:

my $message_id  = $q->param( 'address' );

gives you only one message id, while:

my @message_ids = $q->param( 'address' );

gives you all of the checked values.
