Richard: einsteintoolkit.org has a proper SPF record.
However, einsteintoolkit.org.s9b1.psmtp.com isn't included in it.
More still: einsteintoolkit.org.s9b1.psmtp.com doesn't exist, nor
s9b1.psmtp.com, or psmtp.com
I couldn't find DNS records for any of these domains.
I guess you have a DNS problem, not a postfix problem.
Best regards

Dear users wiser than me (probably everyone),
We have a legitimate domain, einsteintoolkit.org, but I'm getting mail for
einsteintoolkit.org.s9b1.psmtp.com, which postfix doesn't allow through
because it doesn't recognize it as a legitimate domain. What am I
misunderstanding about psmtp and how it works, and does anyone know how I can
get these emails properly delivered?
Any advice is welcome.
Thanks,
