I am new to Zimbra & just I have purchased a domain name example - abc.com & just I have install & configured Zimbra 8.0.5 Server on Cent OS with my isp's public ip in my office & give mail.abc.com & its domain is registered on Go Daddy. Before installation I had done some settings on my domain's Go Daddy Zone File Editor Page into that I have removed default ip of go daddy from A Host record & add my wan ip. After that I have add CNAME record also for mail.abc.com (like mail @). After this at the end I have removed all default MX record & add my server mx record that is mail.abc.com.
My server's hostname also is same as my domain name for mail server like mail.abc.com & I am able to access it also from anywhere in the world but now I am facing issue of receiving emails. Frequently its received the mail some time not.
Below are the example of error where I am trying to send mail from my gmail account to my firstname.lastname@example.org.
