Mail Folder corrupt, What can I do?

I have a VIP user with a corrupt folder. I am running SUSE 7.0. I badly need to make this mail file usable. Are there any tools that can be used to do this? I looked at the mail file in an editor and the very begginig of the file looks binary. Unfortunately, I just put the backup system in place late yesterday and the corruption occurred prior to this. (: Any help is greatly appreciated, Chuck
