> The only real recurring issue is people setting up forwarding to gmail.com/outlook.com/whatever
Since these companies are too big to communicate with us lowly humans, I've given up on the idea of them adding an option to allow this by designating a forwarding domain so the forwarding email server doesn't get punished for forwarded spam.
The fix is super simple: I've set up local accounts for people, and tell them to configure Gmail / whatever to use IMAP to fetch email from the local accounts :)
