You need to put that logic in your view controller. Take vtigercrm/modules/Vtiger/views/ComposeEmail.php as an example and create vtigercrm/modules/YourCustomModule/views/ComposeEmail.php

You need to do something similar to this when processing the request:

$accountId = $request->get('accountid');
$account = Vtiger_Record_Model::getInstanceById($accountId);
$viewer = $this->getViewer($request);
$viewer->assign('TO', $account->get('email'));
