Because if you notice the words "It can verify more than..." you will
realize that what they are doing is connecting to the mail server and
engaging in a conversation that entails using the "verify" command to
test the validity of an address.
More than likely it generates the address prefixes from a pool of words
and or letter/number combinations. If an ISP uses a serialized number
scheme for user accounts then yes I guess you could say they are
Basically they are exploring email addresses prefixes on a per domain
basis by using the mail server as a sieve. By searching this way they
eliminate the need for dns resolutions for multiple domains, which would
precede the sending of actual mail or contacting a given server.
