Just another Linux geek. Configuring Postfix to forward emails via localhost to secure, authenticated GMail. 1 March, 2016. It’s pretty easy to configure postfix on a local Linux box to forward emails via an external mail server. This way you can just send via localhost in your programs or any system daemons and the rest is automatically handled for you. And generate a password specifically for postfix. Sudo dnf install cyrus-sasl-plain postfix mailx. Sudo postconf inet protocols=ipv4. If you don’t...

I was already running stock Lollipop and just kicked up the Ubuntu 14.10 GNOME live image under KVM on my Korora 21 laptop and passed the USB device through. Was really easy to get it going. Actually it was just one command and I was soon booting into Ubuntu, so that was quite impressive.
