If (and this is what I suspect) your primary email address is from a domain you do not own, you may have no good way to resolve the problem. You will not be able to change the SPF/DKIM/DMARC settings for the domain. Given that, you can only try to make FastMail ignore the spam protections. Possibly, whitelisting specific senders might be a partial fix, but you are likely out of luck.

A possible amelioration for this situation is to have a real forward (rewriting all the headers) instead of the redirect type forward used in the past. As far as I know, there are very few services that currently support this. Also, this would obscure the original sender.

The real lesson is that you should not use email addresses from domains you do not own for important emails. The costs of having your own domain are negligible, and allow appropriate control when issues such as you describe occur.
