The "I" part of DKIM is "Identified". That's all it promises. It's a feature, not a bug, that spammers use it.
Which is why DKIM does not really address any concerns. The spammers have reduced its value. I am retired now, but do run my own mail server from home. It is a challenge. Not all static IP's provided by ISP's are outside of "home IP groups", so you will find some of them blocked at some large domains. SPF and DKIM do help, a bit. What I have found really makes the home MTA possible are 1. a "real" static IP 2. proper DNS (A and PTR; PTR must at least exist) 3. tuning your MTA to respect the restraints of various large ISP's Lacking 1 & 2, it is just not worth the effort attempting direct delivery, if you value actual delivery of your email. I would never even attempt such from a peripatetic laptop.
