imap Script - Anhänge speichern, wie ?

[bahnuhr]

Hallo,
es gibt ja hier dieses imap Script:

schedule("*/1 * * * *", function (obj) {
    var MailListener = require("mail-listener2");
    var mailListener = new MailListener({
      username: "abc",    // hier Email Adresse eintragen
      password: "xxx",	      // hier Passwort eintragen	
      host: "imap.xxx.de",
      port: 993, // imap port
      tls: true,
      connTimeout: 10000, // Default by node-imap
      authTimeout: 5000, // Default by node-imap,
      debug: null, // Or your custom function with only one incoming argument. Default: null
      tlsOptions: { rejectUnauthorized: false },
      mailbox: "INBOX", // mailbox to monitor
      searchFilter: ["UNSEEN"], // the search filter being used after an IDLE notification has been retrieved
      markSeen: true, // all fetched email willbe marked as seen and not fetched next time
      fetchUnreadOnStart: true, // use it only if you want to get all unread email on lib start. Default is `false`,
      mailParserOptions: {streamAttachments: true}, // options to be passed to mailParser lib.
      attachments: false, // download attachments as they are encountered to the project directory
      attachmentOptions: { directory: "attachments/" } // specify a download directory for attachments
    });
 
    mailListener.start();
    mailListener.on("server:connected", function(){console.log("imap_connected");});
    mailListener.on("server:disconnected", function(){console.log("imap_disconnected");});
    mailListener.on("error", function(err){console.log(err);});
    mailListener.on("mail", function(mail, seqno, attributes){
        log(mail.from[0].address);
        log(mail.from[0].name);
        log(mail.subject);
        log(mail.text);
        var mailobj = {val:
                {
                    from:  mail.from[0].name,
                    topic: mail.subject,
                    text:  mail.text
                }
            };
        setState("javascript.0.System.Email.Reception", mailobj);
        setState("javascript.0.System.Email.from_address", mail.from[0].address);
        setState("javascript.0.System.Email.from_name", mail.from[0].name);
        setState("javascript.0.System.Email.mail_subject", mail.subject);
        setState("javascript.0.System.Email.mail_text", mail.text);
    });
    mailListener.on("attachment", function(attachment){console.log(attachment.path);});
    setTimeout(function(){mailListener.stop();},20000);
});

Ich möchte nun, wenn eine bestimmte Mail kommt den Anhang speichern.
Müsste doch irgendwie mit diesen beiden Zeilen gehen.

      attachments: false, // download attachments as they are encountered to the project directory
      attachmentOptions: { directory: "attachments/" } // specify a download directory for attachments

Nur wie ?
Hat jemand mal ne Idee für mich.
Danke.
