Send gmail from command line (easier).

gmail.sh

function gmail () {
    $from=<your_email>
    $user=<your_email>

    stty -echo </dev/tty;
    read -p "Password: " passw < /dev/tty
    echo
    stty </dev/tty echo

    opts="-S smtp-use-starttls \
    -S ssl-verify=ignore \
    -S smtp-auth=login \
    -S smtp=smtp://smtp.gmail.com:587 \
    -S from=$from \
    -S smtp-auth-user=$user \
    -S smtp-auth-password=$passw \
    -S ssl-verify=ignore"

    mailx -v $opts $@
}
