Mails being received but also bouncing back in Postfix/dovecot

[Fidelix]

My postfix mail server is receiving messages normally, but is also bouncing the messages back to the sender.

What could be happening?

Here is tail /var/log/mail.log

Please, someone help.

Its impossible to use postfix like that. Every single mail i receive goes back to the sender.
