Hello,

I just want to upload some files (PDF and Image files, partly targeted to an ExtFile object) to Zope once some event occures on my system (triggered by a cron job or a certain mail reaching the system).

You could create a script in Zope where you do what you want to do and give a user the manager role. Then in unix you can call the method by using "wget". You also have to create a ".wgetrc" with the login and password of that user. Don't forget to secure that file in order to avoid that other users can access it. Regards, Josef.
