There is no sure way to do it, but you can try.

1) Call the person or the secretary and ask. It is amazing how many people
   forget about this option.

2) Checking the address if you know the tcp address of the machine. For
   example, you want to check if mail address name@machine.addr is fine:
     telnet machine.addr 25
     vrfy name
     quit
   If vrfy responds with
    250 
   The address in known to the machine

   Sometime, the machine.addr is not a full address but only an MX record.
   you can get the full address by saving the following script in hostlook
        #!/bin/sh
        # this file is called hostlook        
        MXREC=`nslookup <<_END_ | tail -2
        set qt=MX
        $1
        _END_`
        echo $MXREC
   with execute permission (e.g., chmod 755 hostlook), and calling it as 
        hostlook ccl.net.
   Note the period "." at the end of the machine name. It has to be there.

3) Use finger (though it only works with a few machines). E.g.:
     finger jkl@hawkeye.ccl.net

4) Use gopher. Frequently the organizations provide WHOIS database on
   gopher which you can search by name. Go to All Gophers, then continent,
   then country, then organization. If you know, the address of the
   whois database, you can submit queries directly
      whois -h osu.edu labanowski
   If you do not have the whois program, you can still try telned to
   port 43:
      telnet osu.edu 43
   The list of available whois servers can be retrieved from the anonymous
   FTP/mail-server rtfm.mit.edu in the directory pub/whois or via gopher
   sipb.mit.edu You may also find a list of people who recently
   posted something to the Usenet newsgroups in directory
   pub/usenet-addresses/lists} of anon. ftp rtfm.mit.edu.


5) There is also X.500 finder on gopher in Europe. You can also do it by 
       telnet hypatia.umdc.umu.se 23
       login: de
   Then follow instructions (one entry per prompt). For example:
        Simple query mode selected
        Person's name
        :- Schultze
        Department name, * to list depts,  to search all depts, ? for help
