Even though it passed all their checks at the protocol level and even though I used rather strict verification settings for such a new server, Google's algorithm™, in its infinite wisdom, decided that my email was spam.
@amolith Is it separated from the former invidious server?
@tagomago Yep. I bought both a new domain and a new server to make sure any issues with email wouldn't mess with any of my other services and vice versa.
@amolith Microsoft (Hotmail/Outlook) decided to block the disroot email server. And I've been reading sporadic things in different articles that hint at the big email providors, i.e. email as a service, have a tendency to block other email providors with the excuse that that's where phishing emails come from. I wish I'd noted those hints so I could piece a trail together.
It also depends on the ISP you have your servers at
@amolith They often consider all servers they never got mail from before for a certain amount of time as spam.
Sometimes you can shorten that by reaching out to their postmaster address. But yeah, their trust scoring process is rather annoying.
