Primeiro, peço desculpas pelo meu inglês (sou francês).
estou a usarÁrea de trabalho Ubuntu 12.04. Ainda estou aprendendo Shell Scripts, então posso ter cometido um erro muito simples em algum lugar.
Estou tentando escrever um script de shell que me envie um email quando 80% do espaço em disco for usado. (Este script será usado em um cron em um servidor distante hospedado por uma empresa privada)
Para fazer isso eu uso o comando sendmail do Postfix.
O problema é que não consigo nem enviar um e-mail de teste para meu endereço do hotmail usando uma simples linha de comando.
Verifiquei /var/log/mail.log e é isso que recebo (com apenas um comando usado no terminal):

aqui está minha linha de comando:
$ echo foobar | sendmail -i [email protected]
A princípio pensei que fosse a porta que estava bloqueada pelo firewall do Linux, verifiquei usando o comando:
$ sudo ufw status
aqui está o que eu recebo:
État : actif

Não sei o que não está funcionando, por favor me ajude, já estou nisso há várias horas ...
Aqui está o arquivo de configuração do postfix (main.cf):

Não sei se terei que alterar alguns parâmetros desse arquivo, e se for o caso, não sei qual deles... :(
Obrigado pela ajuda desde já ;)
Bem

É bem possível que a porta 25 esteja bloqueada ou não seja usada pelo hotmail. Você pode encontrar melhorreferências, mas tente portas alternativas, como por exemplo, porta 465/587.
