I am having problem sending and receiving e-mail after changing the server. I put my website on a windows server 2008 R2. I updated the DNS setting of my domain and it works fine but now I have problems on receiving and sending e-mail to/from e-mail addresses which are all hosted inside same server address. I tried other e-mail addresses and they worked fine.
So what could be the problem here? is it related to my new server or should I dig into the server which hosted the e-mail addresses?
