    Come installare postfix - Invio mail

    Ciao,
    vorrei installare postfix per poter inviare le mail in automatico dal terminale di ubuntu.
    Seguendo questa guida, ho digitato il comando:
    codice:
    sudo apt-get install postfix
    Ed ottengo questo warning seguito da questi errori:
    codice:
    WARNING: The following packages cannot be authenticated!
        postfix
    Install these packages without verification? [y/N] y
    Err http://us.archive.ubuntu.com/ubuntu/ trusty-updates/main postfix amd64 2.11.0-1ubuntu1
      Could not resolve 'us.archive.ubuntu.com'
    E: Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/p/postfix/postfix_2.11.0-1ubuntu1_amd64.deb  Could not resolve 'us.archive.ubuntu.com'
    
    
    E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
    Grazie in aticipo,
    Ciao
    P.S. La mia versione di ubuntu è 14.04LTS e la sto usando su macchina virtuale con VMware Workstation 12 Player
