    Utilice este comando para enumerar todos los puertos:

    sudo lsof -iTCP -sTCP:LISTEN -P

    Aquí hay una recapitulación rápida:

    25+587 = Postfix (SMTP, SMTPS)
80+443 = Nginx (HTTP, HTTPS)
110+143+993+995 = Dovecot (POP3, IMAP, IMAPS, POP3S)
3792 = SSH (El puerto predeterminado es 22)
111+44012+49968+651+48069+53857 = No tengo idea. ¿Tú sabes?
