This is anecdotal but I decided to host my own sites. I bought the cheapest droplet from digital ocean that I could and I set it up running Fedora. Then I installed Apache, MySQL and PHP so I could run some wordpress sites. The server kept running out of memory and shutting down MySQL so my sites stopped working. I started to learn how to read logs and saw that there is a huge amount of malicious activity directed at my server all the time. Yesterday I installed Fail2ban which meant installing postfix. I got it working (took most of the day) but I can't send emails to my gmail account because I need to set up dkim and dmarc and other stuff. I have a list. But first I have to learn how to do all this stuff. I use Fedora every day at work but I'm obviously no sysadmin and you are so right. All this takes hours and hours to learn and then to stay on top of it. When I was on shared hosting I had a lot less control and options but it was a lot easier as well.

Move mysql to a separate droplet. vultr: $2.50 otherwise you have to change mysql defaults to get things to fit. Great tutorials are out there in general reduce your workers/processes. Why do you need dkim or dmarc to send to gmail? If you send a test php mail does gmail pick it up?

  If I send a test email with postfix - gmail rejects it and gives me a link to their page explaining why I need to add a bunch of stuff so they know I'm not spamming or fishing. Specifically I get this: gmail-smtp-in.l.google.com[173.194.207.27] said: 550-5.7.1 This message does not have authentication information or fails to pass 550-5.7.1 authentication checks.

Are they great? I don't know. Have I tried what is mentioned in many of them? Yes. I still have issues. I don't think it's just mysql though. I think it is a lot of little things that I'm slowly eliminating one by one.

    I spent awhile with loader.io and digital ocean. Putting mysql on a seperate box was huge and allowed me to accept 10x more traffic. This guide helped me back in the day. http://digitaloceanvps.blogspot.com/2014/04/best-configuration-for-512mb-1gb-ram.html?m=1 http://digitaloceanvps.blogspot.com/2014/04/best-configurati... For gmail interesting.. wonder why google trusts me.
