Remove executable files from attachments
Your email system should check incoming emails for malicious content and dangerous file attachments.
If you want to assure that executable files are removed from incoming tickets simply add the following line of code to the 'Receive Script' of your email configuration:
task.setAttachments(helper.getSecuredAttachments('todo4teams removed an insecure attachment:'));
This will irrevocably remove executable attachments before the ticket is presented to the users.
todo4teams will remve all files named *.exe or *.EXE as well as Zip files containing exe-files.
