I also use mxroute. I paid for ten years at once. I only needed it because I wanted a catch-all and my previous hosting provider stopped allowing that.

My email solution for decades has been to have a mailbox separate from my email domain. Currently it’s FastMail. I then give out a different entity@example.com to each entity that needs my email address. I can then shut off (route to null) any address that starts getting spam.

I did order Run Your Own Mail Server because one day I’d like to try.

From the Kickstarter:

Running a mail server is an advanced systems administration skill, though. Mind tricks are not enough. You need to be able to operate a Unix-like operating system, understand logging and TLS, make DNS changes and adjust packet filters. RYOMS takes you through the protocol, configuring Postfix and Dovecot, and the DKIM and SPF and DMARC authentication protocols. (They’re not proper authentication protocols, but that’s what the Empire calls them.) It covers anti-spam measures, mail filters, and virtual domains, all at the command line and with pretty web interfaces. While the reference platforms are Debian and FreeBSD, the Postfix and Dovecot servers and assorted infrastructure work on any open source Unix.

This book does not contain absolutely everything you might ever need to understand running a mail server. Every environment has its oddities. But it does contain the core knowledge that every mail administrator must have. A sysadmin with this orientation can sort out their edges easily enough. Coping with edges is what we do.

yeah, the cynic in me thinks they’re just stoking the fomo to get more sales
