Setting up your own email server is moderately involved, and does
come with some maintenance, some of which can be automated (e.g. SSL
keys).
If you already have a homelab/self-hosting setup, some items such as
hosting your own domain, etc., might already have been taken care of by
you (it is one of the first steps I would do). But before you
start on your journey, I would check wether your IP is not in any of
the abuse
databases, and/or if you are running this from a VPS (many VPS
blocks are by default in the big companies ban lists, with little hope of
getting out or getting an exception). It helps if you have a
static IP, but not necessary, just keep in mind that if your ISP asigns
you a new
IP you might be, suddenly, in an abuse list.
Anyway, I am running my own domain(s) and email server, for many
years from my home IP, and now from a VPS. This is a reasonable step
by step
guide:
https://gist.github.com/howyay/57982e6ba9eedd3a5662c518f1b985c7 if
you start from scratch (it is Debian-oriented). Take things one step
at a time, and test if they are working before going to the next
step. The postfix.org manuals are there for more in-depth info,
specifically
when it comes to hardening your postfix/dovecot (and bind9 or other
public-facing DNS server if you fully self-host).
I always liked having my own domain and mail server, esp. so I
can give out on-the-spot alias emails to websites and vendors. If they
mess up
QQ(i.e. data breaches or selling my info), I can easily ban that
recipient email. Having a backup email at your email provider of choice is a
good thing to have, though... I had to use a `professional`
provider in a handful of cases in the last 15 years or so that wouldn`t
accept my
home email.
Hope this helps, and I wish you good luck on your journey!
