Feel free to move this thread if it does't belong here, but I thought it was the closest match. I want to start a service where I deliver each user a 5mb zip file a day (probably 300 users). How could I do that? Putting it on FTP and distributing the link is not an option, cause I want to watermark the files to have some means against abuse and leakage. Are there email programs out there that would do that on autopilot? Thanks!
