TIPS Exim4 doesn't seem to be able to deliver mails to one.com?

[Fribse]

Not sure how to understand the exim4 log:

But for me it seems that it complains that the [email protected] address is not the same as [email protected] (which it obviously isn't :-D ) But how do I fix that?

Did you put FQDN in the / etc /hosts file with your external IP address? That's the /etc directory and file hosts

Other than that, exim is not a mailer I am familiar with.

 

[Dr. Kupka]

Enter in /etc/email-addresses:

root: [email protected]

Hmm, no change. I did find the noreply.incrediblepbx.com in the hosts file for 127.0.0.1 but changing that to my domain didn't change anything.
I also added the suggestion by @Dr. Kupka which also didn't change it, exactly same message.

Did you restart Exim after making updates?

Did you restart Exim after making updates?

Yes, I did the exim reconfigure and restart

Ok, I started over, and now the exim4 works, I think the first input where the guide says use default and it shows incrediblepbx as mail hostname, I changed that in this brand new install, and that made it work for the test mails.
Now I just need to configure all the rest again
