Check your DNS server logs for reverse lookups against the client's IP address (or against the IP address that the client is seen as by the FTP server, if you're doing any NATing). If this turns out to be the case, consider putting up an rwall service so that reverse lookups for internal user IP addresses are given a generic response. Info on one such service at http://cr.yp.to/djbdns/walldns.html.
