The logic isn't even that bad. SPF and DKIM serve to prove to the email who the sender is. That doesn't mean much if the sender is a spammer. Verifying identity claims is only the first part in checking email for spam, the harder part is checking if that identity is someone you trust.
When you email Outlook or Google, you're better sending more than a few every single day, and the recipient better manually drag those emails from their spam folders to their inbox, or they're all being learned as spam.
The domain is new and didn't send a single email until I tested it.
Edit: The domain is actually a bit old but was parked/inactive for a while, though the email was used only for receiving.
Those email services will usually have no trouble with replies to emails sent from their service, so if you get someone to email you first you'll save them the trouble of dragging your email from their spam folder to their inbox.
Then it checked the DKIM signature on the message it REWROTE ON ITS OWN and decided that the signature didn't match, and rejected my email.
Corporate email stacks are hell.
