That may indeed be the case, and ideally you should have a reverse DNS
entry for your machine (in particular, IRC servers tend to be pretty pissy
if they can't do a reverse lookup).  However, I don't understand why somone
would set up an FTP server to require this...  In fact, I don't really
understand why *ANYONE* relies on reverse information.  Personally, I think
the whole paranoid reverse/forward lookup like done with tcpwrappers is

I can understand why you would do it if you rely on the reverse name for
authentication, but I don't think that's a strong method of authentication
