    you will find you get a ton of spam if you use the settings in the "perfect setup" guide.

    This is because the file "/etc/postfix/main.cf" for postfix needs editting as follows.
    BTW THIS ALSO WORKS FOR OUTLOOK CLIENTS ON WINDOWNS:-


    # See /usr/share/postfix/main.cf.dist for a commented, more complete version


    # Debian specific: Specifying a file name will cause the first
    # line of that file to be used as the name. The Debian default
    # is /etc/mailname.
    #myorigin = /etc/mailname

    smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
    biff = no

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

    # Uncomment the next line to generate "delayed mail" warnings
    #delay_warning_time = 4h

    # TLS parameters
    smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt

    # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
    # information on enabling SSL in the smtp client.

    alias_database = hash:/etc/aliases
    myorigin = /etc/mailname
    #mydestination = server1.xxxxs.com, localhost.xxxxxxxxs.com, , localhost

    mynetworks = 127.0.0.0/8

    smtpd_tls_received_header = yes
    smtpd_tls_session_cache_timeout = 3600s
    tls_random_source = dev:/dev/urandom
