This isn't a very good solution.  Some sites perceive finger information to be a
security risk and turn off fingerd.

Anonymous ftp passwords depend on user-supplied information, and it's a simple
matter for any anonymous ftp user to supply a bogus email address, whether their
using an ftp client or Netscape or whatever.  The only semi-reliable information
ftpd receives at login is the originating site, and even that is open to
question, given the various types of spoofing that are possible.
