Use your domain for your primary email address, have some regrets about it, but never be able to walk away..
Soooo. I’m dumb. I host my overseerr on my domain that just routes to my local IP for my local desktop. How do I get email on this domain without spending dumb money on an email hosting server?
Linux + postfix (SMTP) + dovecot (IMAP and POP3) + SPF + DKIM on the host
Point the MX record for your domain to your IP address
Contact your ISP and ask them to set the PTR record for your IP to your hostname
Mail can be handled by a very low end computer, a raspberry pi can handle email for a small number of users
If you have a specific mail machine you would forward the ports you use to that host on your router.
