I have setup a Exchange Server in my office. I'm able to send mail but unable to receive it.
I have registered domain name = bdaconnect.in and A records pointed to my static ip = 126.96.36.199 mail.bdaconnect.in and MX records is = mail.bdaconnect.in
I named my Exchange Server machine = mail.bdaconnect.in.
When I create a user and send mail over inter, they receive it but when I reply that main, my exchange user didn't net it and I also open the ports of my firewall 25,110,143
