Not bad? In my opinion, it is tragic

Because you have to visit these 132 a day. And my position is that these 132 should not even be considered SPAM.

Anyone have any ideas where to put one of the two options above?
I did so. I bought a .pl domain. It costs about PLN 10 a month. Acceptable for me. And I use it for many other things. In addition, a mail server on a microcomputer, which has recently been built a lot, which, running 24/7, consumes electricity for PLN 2-3 a month.
Preset domain-to-IP (reverse DNS) validation, spf record checking, gray lists, blacklists.
Disadvantages:
- it costs me ~ PLN 15 a month
- some fun with the configuration at first
- the server is only as accessible as I have electricity at home and a working link. But what is it? 99.9% of the time. It's OK for me.
Benefits:
- I don't know what SPAM is. I don't look in the spam folder. 99% are not allowed to pass anything to the server, because something is grossly wrong.
- unlimited number of mailboxes, aliases, time boxes, black hole mailboxes, etc.
- spammers spam a large number of mail service providers. They practically do not know about me, because it is a server for ... 2 people.
- I have individual aliases, e.g. for each online store I use. How do I get SPAM for a given alias, so who should I "thank". It takes 1 minute to delete an alias.
- possibility to set any other considerations - number of sessions per IP. Number of sessions from a given IP per minute. Blocking IP after X login attempts. Etc, etc.
