Hmm... strange. No idea what goes wrong there...

The dns query is done and there seems to bee an answer, but it
still doesn't work.... All the proxy does there is:

                ctx->magic_addr = socket_str2addr(p, INADDR_ANY);
                if (ctx->magic_addr == INADDR_ANY ||
                    ctx->magic_port == INPORT_ANY) {
                        client_respond(501, NULL,
                                "Invalid destination in user name");
                        syslog_write(U_WRN,
                                "bad 'USER@' dest '%s:%s' from %s",
                                NIL(p), NIL(q), ctx->cli_ctrl->peer);
                        client_reinit();
                        return;
                }

If you take a look to the log messages (e.g. in one of your other mails),
the string variable "p" used in syslog_write contains valid hostname...
The socket_str2addr calls gethostbyname...

An other posibility is, you have a broken IPPORT_FTP or INPORT_ANY
definition in some header file? IPPORT_FTP should be defined to 21
and INPORT_ANY to 0. If it is not defined, the proxy defines it...
