I have taken a look at my logs:
This is the error:

Doesn't your ISP mess with DNS, e.g. intercept it?
I added:
[email protected] OK
to sender_checks and this seems to have resolved this issue.
I'd advise to add IP 45.90.5.195 to client_checks instead.
...at least according to your previous mail at:
https://marc.info/?l=postfix-users&m=178097029875686&w=2
since seems you missed something in your paste below...
smtpd_helo_required = yes
cidr:/usr/local/etc/postfix/client_checks, check_sender_access
hash:/usr/local/etc/postfix/sender_checks, check_sender_access
hash:/usr/local/etc/postfix/sender_access,
