I can not send or receive emails to the @rs.iq domain.
My web host says this is because the rs.iq domain has not been configured correctly at their nameservers. The MX record they have entered is just an IP address. They said this will cause issues sending to them as MX records should be a domain address rather than IP.
I understand their comments, but if I use a gmail email address I can send and receive emails to this domain. I have mentioned this to my web host, but they said they don't know how it is possible via gmail, but there is no way I can make this happen via my hosting environment.
I know it's generally best if rs.iq resolve the domain issue, but this is out of my control. My contact at rs.iq say that they have 200 other clients who do not have any problems with emailing them and receiving.
To give you a bit of background on my set up. I have a VPS server that runs cPanel and WHM (Web host manager).
Please can you help me find a solution or at least recommend a work around?
