@aral @cancel I don’t think it is that bad. I am using several self-hosted mail servers, just some of the acronyms are implemented and it mostly works (I rarely hear about delivery issues). I rarely write to unknown/new people, though.
Yes, it is a bit of a chore, esp. when someone gets pwn’d and you need to persuade all the block lists from unblocking your servers, but that fortunately does not happen often.
Currently, most of the spam I receive comes from gmail anyway, so I am a bit inclined to treat them as the most spammy server. And someone using outlook told me they just always check both inbox and spam, since the filter is really eager.
So yeah, not great, but definitely not terrible either, at least from my experience.
