A Survival Guide for the Small Mail Server
I think it is absolutely hilarious (and infuriating) that in their opening paragraph they forgot to list spam blacklists, like themselves, as being perhaps the biggest hurdle for small companies and individuals running mail servers.<p>I ran a mail server for almost five years, and 9/10 of the issues I had to resolve were various anti-spam blacklists or individual hosts blocking our emails and then having customers complaining because we never emailed them.<p>There was never any reason given for the blocks, and our logs didn't show any outgoing spam. However all of these spam blacklists would accept a "donation" if you didn't want to wait the 24-72 hours for them to unblock you. Essentially it is a shakedown.<p>I've just given up self-hosting and I recommend others do the same. The issue isn't the spam, it is how much time you'll waste fighting the anti-spam blacklists and large email hosts. A job better left to e.g. SendGrid or SES.<p>PS - We sent tens of thousands of emails a day.
