Default Problem with sending emails outside of own domain.


Whenever I try to send emails from my local domain to my gmail; I get an error
Jun 19 20:13:56 ubuntuserver postfix/smtpd[3150]: NOQUEUE: reject: RCPT from localhost.localdomain[]: 451 4.3.0 <*********@gmail.com>: Temporary lookup failure; from=<admin@example.com> to=<*********@gmail.com> proto=ESMTP helo=<[]>
How come I'm getting this error? 451 4.3.0 Temporary lookup failure.
Tried googling already and it didn't really help.

I set up my Ubuntu-server using The Perfect Server - Ubuntu 12.10 (Apache2, BIND, Dovecot, ISPConfig 3) Howto
Sending emails within my own domain is no problem!

Kind regards;
