I am an enterprise programmer by day and I've been running mail servers for 20 years both for hobbies and for private use. I rarely spend more than an evening per year, mostly to keep up with new developments in that space. A few years ago I deployed DMARC. Last year I registered in postmaster tools at Google, Yahooo, Yandex and a few others. This is it.
