Primero, pido disculpas por mi inglés (soy francés).
Estoy usandoEscritorio Ubuntu 12.04. Todavía estoy aprendiendo Shell Scripts, por lo que es posible que haya cometido un error realmente simple en alguna parte.
Estoy intentando escribir un script de shell que me envíe un correo electrónico cuando se utilice el 80% del espacio en disco. (Este script se utilizará en un cron en un servidor distante alojado por una empresa privada)
Para hacer eso uso el comando sendmail de Postfix.
El problema es que ni siquiera puedo enviar un correo electrónico de prueba a mi dirección de hotmail usando una simple línea de comando.
Revisé /var/log/mail.log y esto es lo que obtengo (con solo un comando usado en la terminal):

aquí está mi línea de comando:
$ echo foobar | sendmail -i [email protected]
Al principio pensé que era el puerto bloqueado por el firewall de Linux, lo verifiqué usando el comando:
$ sudo ufw status
esto es lo que obtengo:
État : actif

No sé qué es lo que no funciona, por favor ayuda, llevo varias horas en esto...
Aquí está el archivo de configuración postfix (main.cf):

# line of that file to be used as the name. The Debian default

biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no

mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all
No sé si tengo que cambiar algunos parámetros en ese archivo, y si es el caso, no sé cuál... :(
Gracias por la ayuda por adelantado ;)

Es muy posible que el puerto 25 esté bloqueado o no sea utilizado por Hotmail. puedes encontrar mejorreferencias, pero pruebe con puertos alternativos, como por ejemplo el puerto 465/587.
