I cannot seem to work this one out.
Client is using zoneedit for DNS because he is a reseller and does not want to use our DNS.
Now I cannot send mail to him. Nobody can. The error I get back when trying to send him mail is:
config error: mail loops back to me (MX problem?)
554 5.3.5 ... Local configuration error
As far as I know he can SEND mail just fine.
He has full dns/mx settings at zoneedit. He gave me his pw and I checked/corrected myself.
mail.hisdomain.com --->IP address
domainname -->mail is send to -->mail.hisdomain.com
Same setup on my server as well.
Somewhere I am going wrong thoug
