====== Store mailscanner attachments only once ======

If you use the mailscanner in vtigercrm 6 you probably recognized every mail attachment is stored multiple times in documents.
This isn't necessary.

To modify this, please apply the following modification

==== File: /modules/Settings/MailConverter/handlers/MailScannerAction.php ====

** Search **
<code php>
var $STORAGE_FOLDER = 'storage/mailscanner/';
</code>

** Insert after **
<code php>
private $_notesId = array();
</code>

** Search **
<code php>
function __CreateTicket($mailscanner, $mailrecord) {
</code>

** Insert after **
<code php>
$this->_notesId = array();
</code>

** Search **
<code php>
// Create document record
$document = new Documents();
$document->column_fields['notes_title']		 = $filename;
$document->column_fields['filename']		 = $filename;
$document->column_fields['filesize']		 = mb_strlen($filecontent, '8bit');
$document->column_fields['filestatus']		 = 1;
$document->column_fields['filelocationtype'] = 'I';
$document->column_fields['folderid']         = 1; // Default Folder
$document->column_fields['assigned_user_id'] = $userid;
$document->save('Documents');
</code>

** replace these lines with **
<code php>
				if(!isset($this->_notesId[$filename])) {
					// Create document record
					$document = new Documents();
					$document->column_fields['notes_title']         = $filename;
					$document->column_fields['filename']         = $filename;
					$document->column_fields['filesize']         = mb_strlen($filecontent, '8bit');
					$document->column_fields['filestatus']         = 1;
					$document->column_fields['filelocationtype'] = 'I';
					$document->column_fields['folderid']         = 1; // Default Folder
					$document->column_fields['assigned_user_id'] = $userid;
					$document->save('Documents');
				 
					$this->_notesId[$filename] = $document->id;
				} else {
					$document = CRMEntity::getInstance('Documents');
					$document->retrieve_entity_info($this->_notesId, 'Documents');
					$document->id = $this->_notesId[$filename];
				}
