Not able to send mails to gmail from my domain

Hi past 2 days from my linux mail server not able to deliver mails only to gmail server getting below error


The ip you're using to send mail is not authorized 550-5.7.1 to send email directly to our servers. please use smtp relay at 550-5.7.1 your service provider instead. Learn more at 550 5.7.1 http://support.google.com/mail/bin/answer.py?answer=10336 it5si32975260pbc.95 -gsmtp (in reply to end of data command )

Go to your ISP support website and find out how ordinary folks are supposed to
set up their e-mail. Take note of what they are supposed to specify for smtp
server. Edit your postfix configuration and set your relayhost parameter to
that smtp server.
