Proton Mail provided Swiss authorities with payment data for defendtheatlantaforest@protonmail.com — the account linked to Stop Cop City protests in Atlanta. The FBI obtained this information through a Mutual Legal Assistance Treaty request on January 25, 2024, identifying the activist behind the anonymous account through their credit card identifier.
Even some commercial less well known mail providers are sometimes blocked by big players like gmail and outlook for anti-spam reasons.
Just set up dkim, SPF, and dmarc properly and you should be good.
Nope. Take for example Gmx.
Due to the heuristics some of the providers have, such as Microsoft, they will start classifying mail sent from gmx as spam and auto move it to people’s spam folder. They have developed their own internal trust metrics and these periodically just spambin low trust servers
I can’t say either way, I manage dozens of M365 tenants myself and usually what trips it is lack of SPF/dkim/dmarc or bulk senders. But again, not common to have independent mail providers these days but even Microsoft still makes Microsoft exchange server…
Self hosted my mail for decades, the only issue i’ve had is Hotmail/outlook, who have blacklisted my IP with no way to unblock it.
Gmail is pretty good
My mail provider isn’t that big. We got blocked by both outlook and gmail, but I duckduckwent a workaround which worked. Something about editing some mail record somewhere. Can’t remember what, I’m afraid.
Yeah you need a bunch of “optional” records SPF DMARC DKIM PTR (if possible)
