Re: Invalid MX record

Tech-Archive recommends: Fix windows errors by optimizing your registry

Also, if we simply have to add a record to expose our domain to all our

not receive any. Is there another alternative to the problem, like just
adding/allowing certain domains that we are having the problems with. Right
now I have only 3 domains that are clients ours that we cant reach by email.
