# Tested on OpenSuse 11.4 & 12.1

configure () {
    if [ `rpm -qa | grep -ic postfix` -lt 1 ]
        echo "Postfix is not installed. Exiting..."
        exit 1


    read -p "Enter your Gmail address " gmail_address
    read -s -p "Enter your Gmail password: " gmail_password

postconf() {
    if [ -f ${POSTCONF} ]
        cat >> ${POSTCONF} <> /etc/postfix/sender_dependent_relayhost <> /etc/postfix/tls_per_site <> ${SASL} <> ${MAINCF} << EOF
smtp_tls_CApath = /etc/ssl/certs

    c_rehash /etc/ssl/certs

    /etc/init.d/postfix stop

    Hi, i want to switch from yahoo to gmail but i have too many contacts and emails in yahoo and it would be very very difficult switching. Is there any way i can configure my emails so that everything that is sent to my yahoo account will automatically send to my gmail?

    I made somebody mad obviously, and somehow they shut down my gmail. I hate Google anyway, but honestly, I can’t think of anything they object to. It has to be personal, somebody that doesn’t like me, told Google to shut down my email. I need my email addresses. Anybody have any bright ideas?

  • Picean says:

    In gmail, I know it is possible to forward anything you receive to another email account automatically. However, I want gmail to automatically forward anything I receive to two email accounts…
    Is this possible, and if so, how would it be done?

    I know that somehow I had my gmail forwarded to my yahoo account, but it’s out of control. I had over 5,000 messages. I want to stop forwarding my gmail to my yahoo account, but I can’t remember how I set it up to begin with.
