For awhile I had trouble with Yahoo and a couple of others. I also had to get off a couple of spam lists. There was one big service that troubled me for years, can't remember which. But, the years went by and I guess my IP address got a better reputation. I haven't had a deliverability problem in years. Maybe it's because I got better at the SPF's, DMARC's, etc. I will say that I think it's an internet sin that these big companies make it hard for individuals to run their own servers. It seems like an attempt to make a corporate monopoly. My server has never been used for spam a single time. There is no reason I should not have been able to remedy problems instantly.
