As mentioned previously, I’ve recently moved this domain over to Slicehost. What follows is Part Three of a guide, compiled from my notes, to setting up an Ubuntu Hardy VPS. See also Part One, Part Two, and Part Four.
Last week I moved this domain’s email to Google Apps. Slicehost has a guide to creating MX records for Google Apps. I have a couple other domains with Google Apps, along with a couple domains hosted locally with addresses that simply forward to my primary, Google hosted, email. I also need to send mail from the server. To accomplish all of this, I use Postfix.
