gmail silently drops emails (while reports smtp 250 accepted) - they could just as easily report that it's blackholed. spammers already do get through their fancy AI filters.
microsoft proactively blocks half of the world, rejects the incoming mail, and sends the sysadmin on a wild goose chase to get the IP/domain/whatever allowed. then you diligently register, and wait. and then no signal from them, and the problem still persists.
so big corps, small shops, everyone and their dog flocks to the good old microsoft/google duopoly.
and at this point if someone asks what to use for email knowing ... well, it's hard to not recommend folks to just use google workspace and have some kind of backup ready for when G bans their whole account just because.
I hope at some point the routine crushing of smaller providers gains the attention of the competition and markets authority, or its equivalents. It is crazy how Google and MS use their market power in this way and get away with it.
