Although I adore running my own mail server, I was curious about Google Apps for Work, specifically Gmail for Work. Could it block spam as effectively as my own insanely-aggressive rig? Also, if I ever got tired of managing my own server or (gasp) something hugely disastrous happened to my infrastructure, I figured Google Apps could serve as an apposite alternative or fall-back solution. If nothing else, perhaps I could add this experience to my IT resume. They offer a free 30-day trial, so I didn't have anything to lose.
I don't think it's necessary to go into excessive detail because I'm sure Google Apps for Work is already well-covered on the web, but long story short--it's an incredible bargain. Google offers a tremendous number of features for the price--to the point it can be overwhelming. In the end, however, I did miss the customizability of running my own mail server, so I asked Google support a couple questions. My questions are below along with their answers.
