I run Postfix & Dovecot (with SPF, DKIM, DMARC, DNSSEC, TLS) from my home network with a remote backup just in case it goes down, as well as my own DNS servers.

I had to ask my ISP to disable some rules on their end and pay a fee to have a static IP address, but overall it was pretty painless. Though I can imagine some providers being much worse.

After the initial hurdle of setting everything up in my experience everything went mostly fine. I had to whitelist my domain on Microsoft's site, but Gmail and Yahoo worked fine from the start. I haven't had a problem since. My university teachers receive my email just fine, so did my co-workers before I was given a corporate email address.

Is it worth it? Maybe not. It was more of a learning experience for me, but I find it works just as well as any other provider I've used. At least for now.

As others have said there are lots of outdated guides. I found the Archlinux Wiki and the manpages to be the most useful resources. Also please stay up to date on the software.
