[Pkg-exim4-users] Getting 550 relay not permitted, I tried all sorts of things still getting error

[Nate Homier]

My problem: Delivery to the following recipient failed permanently:

     public at universal-mechanism.org

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server
for the recipient domain universal-mechanism.org by homier.dyndns.org.
[184.166.103.9].

The error that the other server returned was:
550 relay not permitted

All email is rejected.

2 mx records.  mxin.mxes.net which receives and sends, it's my
smarthost.  And homier.dyndns.org which has EXIM4 running and where the
problems are.  Check my DNS record below.

I have my domain universal-mechanism.org and I use Tuffmail as my
smarthost, meaning Tuffmail receives and sends mail on behalf of my
domain via an mx record.  Recently I decided to setup EXIM4 with
Internet site selected in exim4-config.

Exact settings are:
internet site; mail is sent and received directly using SMTP
Mail name: universal-mechanism.org
Listens on all interfaces
Other destinations for which mail is accepted:
saturn.hyperion.local; homier.dyndns.org; universal-mechanism.org
Domains to relay mail for:
universal-mechanism.org; homier.dyndns.org
Machines to relay mail for: blank

My DNS is as follows:
