Another potentially useful workaround is to configure ProFTPd to run out of inetd, using TCP Wrappers to enforce paranoid DNS checks. This way you can have your cake and eat it too.
One can probably bypass ftpd ACLs in such configuration - it should be possible to provide valid DNS/rDNS mapping when tcp wrapper is asking (using short TTL) and then give ftpd some other host name. It might be fine if you just don't want visits from unregistered hosts. -- Krzysztof Halasa Network Administrator
