Hello we are hosting here own web site. We got our own DNS server.
I remark that some site whoe are not our web site, direct our Web server and MX records on our mail server.
It's there a way to prevent this kind of attack ?
I meen :
Suppose i host thoses web sites : with the mx record to
a.com b.com c.com d.com
A web site like
foward all there request MX and Web to my server. There is no DNS way to valid the right mx server and the right Web server ?
