Restricted Access Question

Currently any time someone submits an e-mail to us on our website I have a script that is setup to write the contents of the e-mail to a file, so that we can use that file to keep track of things incase the e-mail send fails, or our e-mail servers at our company are down, whatever. The text files (one long log, two text files 'cause there are two forms on this particular site) are stored in a folder all by themselves off the root. Let's call it the /email folder.

Now, while ensuring that we can still write to that folder when an e-mail is submitted, how do I restrict access by others to it? If at all possible, I would like it if it could be accessed by just the office IP, that way we could still access them, but no one else could.

n/m, figured out how to restrict folder access by IP, thanks anyway! <smiles>
