Can't send emails [edit: not related to Migration Tool]

I bought the Migration Tool yesterday and successfully migrated the old server to a new today. However, something must have gone wrong because now I can't send emails with the new server. I get "SMTP Error (550): Failed to add recipient.".

I have set this Debian 8 (Jessie) using the Perfect Server setup, then run the ISPconfig Migration Tool. Both the old and the new server is running ISPconfig3.

Any ideas what could be wrong?

 

Latest test from /var/log/mail.log :
Test setup: login into webmail on the host. Send an email from a local email address to a remote email address.

All of it or the things that was changed during the installation of the server? Here is what was changed:

I was not able to upload files with a .cf extension, so please disregard the current extension .txt .

 

Oh. Ok. Well, I tested it and copied it from the guide for the Perfect Server, restarted the postfix service, but the problem remains. Is this info stored somewhere else too?

 

Ok

 

Message received, so that worked.

By sending an email to an external domain. It results in this:

Regarding the /etc/hosts file: there are four IP addresses at this server. How should this be reflected in the hosts file? All pointing to the same hostname?

In main.cf , inet_interfaces was set to 127.0.0.1 . It didn't help though to change it to all.

(Thank you for all your assistance so far! It's much appreciated!)

 

I am afraid that the problem still remains. It is still "550 5.1.1 <[my-receiver-email]>: Recipient address rejected"
