A few months ago I had this problem but I found out that my issue was with not having a PTR record for my mail server and since then I acquired 5 static IP's, with the proper DNS entries, MX record and PTR record for the reverse lookup for my mail server and I an able to send email just fine, but I am not able to receive email I keep getting the below error in my mail log. This is a new installation with minimal to no changes to the main.cf file.
mail postfix/smtpd[31690]: NOQUEUE: reject: RCPT from mail-iy0-f176.google.com[209.85.210.176]: 554 5.7.1 <mail-iy0-f176.google.com[209.85.210.176]>: Client host rejected: Access denied; from=<mygmail40@gmail.com> to=<myname.mydomain@mail.mydomain.com> proto=ESMTP helo=<mail-iy0-f176.google.com>
Apr 10 18:45:18 mail postfix/smtpd[31690]: disconnect from mail-iy0-f176.google.com[209.85.210.176]
I can see the emails hit the server and I can receive emails between users in the one domain I have created but, when email coming from the internet it does not work. When testing my email from MX tools out on the internet I get just get this.
