I have a reseller account in www.datacenterperu.com. This website have servers in The Planet (a friend of mine is the owner). My reseller account is www.balitas.com.

I have a customer in my reseller account named www.perulogistic.com.pe. This customer have problems receiving emails, he told me he not receive emails from different clients.

If you see http://www.dnsreport.com/tools/dnsreport.c...acenterperu.com you noticed that www.datacenterperu.com not have problems with dns. But if you see http://www.dnsreport.com/tools/dnsreport.c...ain=balitas.com you will see problems with dns, but I use the same dns of www.datacenterperu.com!

Please help me to solve this problem and tell it to my friend and fix the problem in his server.

Regards

An administrator of another server told me that we need to activate the relays. What do you think?
