Topic: I can't send mail to gmail addresses.

Hello,
I did an iredmail setup from scratch. I have configured dns settings etc properly. My service provider opened port 25 for the ip address. The ports used on the firewall side are open. (25,587,465 etc.) Despite all this, I cannot send e-mail to gmail addresses. I am also attaching my mail-tester result.
The error I get when I try to send mail to gmail address is as follows:

host gmail-smtp-in.l.google.com[74.125.133.27] said:
     550-5.7.1 The IP you're using to send mail is not
     authorized to 550-5.7.1 send email directly to our servers. Please use the
     SMTP relay at your 550-5.7.1 service provider instead. Learn more at 550
     5.7.1 support.google.com/mail/?p=NotAuthorizedError

     end of DATA command)

well, then just setup a relay for gmail, that's not a big deal
