What's the sender's email address? Does it have a FQDN on the right side?
What's the value of myhostname in /etc/postfix/main.cf?
What's the output of

hostname -f

?

root@mail:~# hostname -f
mail.gabrix.ath.cx

root@mail:~# hostname
mail

The mailname is gabrix.ath.cx which goes behind the @ gabrix.ath.cx correct ?

This isn't correct. Please run

postconf -e 'myhostname = mail.gabrix.ath.cx'

and restart Postfix.
