Trackbacks on Scheduled Posts

I tend to schedule posts to go up at various times throughout the day, but I’ve noticed that my trackbacks on scheduled posts tend to go out before the post is actually visible on the blog.

I know there’s a plugin out there to delay trackbacks going out until the scheduled post goes up. I’ve searched for it, but haven’t found it. If someone out there knows where to find this plugin or how to do this another way, I’d appreciate knowing.

Thanks!
