Consulta puerto 25

[zerobatu]

estimado,
buenas tengo la siguiente consulta tengo una VM con debian 6 la cual ocupo
para estudiar programacion y meterle mano a debian bueno resulta que se me
ocurrio mirar que puertos tengo abiertos con nmap y me salto que tengo el
puerto 25 abierto, el sistema lo reinstale hace poco por un problema de la
VM y no recuerdo a ver instalado ningun servidor de correo.
como puedo saber que servcio me esta ocupando este puerto.

les dejo los comando que he ejecutado a ver si me pueden ayudar. desde ya
gracias
