<p dir="auto">I've been running my own mail server since last century and haven't run into any problems with big email providers not accepting my mail. What problems did you have?</p>

<p dir="auto">You may just be lucky. Normally, they want at least DKIM and SPF records and you might still be greylisted.</p>

<p dir="auto">Yes, I did need to create SPF records in my DNS, but aside from that, nothing else. I didn't need DKIM. I also make sure there are no open relays, of course.</p>

<p dir="auto">Or, worse, and happens to me on G-Mail, your e-mails are considered spam and you'll be silently ignored unless the users check their explicitly. I've had this domain around 25 years and my business one for 15 and you still get occasional rejections because you might be a spam pusher…</p>

<p dir="auto">That's a risk, perhaps no more so with you own mail server, though.</p>

<p dir="auto">If one considers that the internet was initially conceived to avoid the single point of failure risk, we're getting closer to unwinding it with one of the key and most reliable forms of communication e-mail. It's not beyond the realms of possibility that within the next couple of years nearly all business communication (outside China) will run on either Microsoft or Google servers, at which point they'll be able to extend and then extinguish protocols…</p>

<p dir="auto">We've moved quite far from the original principles (openness, complexity/enforcement at edges, no middleboxes interfering, narrow waist). Email is a casualty of its design principle that anyone can send to anyone. Perhaps X.400 was right after all :-).</p>
