If you are running spam filters then don't they need constant attention?

Dont you need to keep on top of DMARC reports?

I am not sure about other mailsevers but with Mailcow I occasionally (once per week maybe) get spam notification (release/delete call to action) that I just click and that is all. I have DMARC reports coming in but as far as I remember they are about my own server outgoing emails. So no, I do not think so.

As for my own emails they were rejected maybe by just few times. But I do not use email much - just some personal communication. I am not running marketing campaigns that places my IP on some blacklist.

I think I just one time was on one of spam lists. I just emailed them or applied for removal via some webform and they removed the entry pretty much instantly. I do not remember other problems.

As far as I understand this article it talks about different IPs in SPF. This is just one machine with one IP. I do not send big quantities of emails from other servers. And even if I would need to I would just create mail box and send emails via that mailbox.
