How can ich deactivate the upload of an attachment to my server? The users just have to send the file directly to my emailadresse - without saving on my server. If an user send an attachment, he got a php error-message (trying saving the file on my server), but the file was successful transfered to me. The version of my blog is 2.3.3 an the version of cform is 8.6. Thank you!
you can't. every file transfered to from the users browser to your server needs to at least temporarliy be stored on the server (PHP tmp folder).
if you want to avoid having the file being copied to your personal folder, then you need to go into lib_nonajax.php and comment out the "move_uploaded_file()" call.
