I've been struggling with the tradeoffs in keeping Google as my email (among other things) provider. I own a few VPS's and have plenty of hardware that could serve as a private server. What has kept me from hosting my email up to this point is the fear of being inadvertently blacklisted by something like Spamhaus, downtime from Comcast (my ISP) making service intermittent, and generally having the email server management take over my life. In short, the same issues that affect many here by evidence of the recent chart of Y Combinator companies' hosting decisions (<a href="http://jpf.github.com/domain-profiler/ycombinator.html?2011" rel="nofollow">http://jpf.github.com/domain-profiler/ycombinator.html?2011</a>).<p>I could host my own email on my VPS, but going through the trouble of that - it seems to make sense to just go ahead and host on a box I fully control.<p>To this point I admit I have had no issues with gmail or Google apps, both of which I use. But the landscape seems to be changing and I'm curious if anyone is considering migrating to their own hardware and what tools, etc. they are employing to make that process easily manageable as well as effective. I use email for sensitive business discussions, but the security required is tempered by the obvious fact that if the email doesn't get there, it's less than worthless.<p>I do have PGP setup, and I thought that this would be a good tradeoff while using a third party provider - but it is nearly impossible to keep partners and clients active in using it, if they use it at all.<p>The concept of the Freedombox (freedomboxfoundation.org) seems interesting, but academic at this point.<p>Anyone running their personal email servers care to comment on the overhead? Would a simple Postfix, Dovecot, Roundcube install with Spamassassin suffice? What are the pitfalls? Not worth the tradeoff of using Google Apps?<p>I'm thinking about keeping my websites on a VPS and using a MX record to point to a private, dedicated email server I keep in my house or other private property. Anyone running a similar setup?
