manda un e-mail a la dirección de correo que dudas si existe, si te lo devuelve pues ya sabrás que no existe
Vale, también puedes hacerlo sin enviar un e-mail. Miras los servidores dns de hotmail:
[alex@ns2 ~]$ nslookup -q=mx hotmail.com
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
hotmail.com mail exchanger = 5 mx3.hotmail.com.
hotmail.com mail exchanger = 5 mx4.hotmail.com.
hotmail.com mail exchanger = 5 mx1.hotmail.com.
hotmail.com mail exchanger = 5 mx2.hotmail.com.
Te conectas por telnet al servidor correo de hotmail y miras si el el buzón existe:
[alex@ns2 ~]$ telnet mx3.hotmail.com 25
Trying 65.55.92.152...
Connected to mx3.hotmail.com (65.55.92.152).
