Message not sent. Server replied: Requested action aborted: error in processing
451 4.3.5 <localhost[::1]>: Client host rejected: Server configuration error

 

i got a new pc and trying to turn this into new server, i may have installed sendmail after installation of ubuntu 14.04 ant the perfect server, tried to uninstall sendmail and reinstall postfix.
