Unrouteable domain response when trying to send mails from my server acounts
I need help because I´m in a big trouble. I´m actually acting as a reseller, but from 2 mounths, my customer are having problems sending emails to any domain which is hosted under "servidoresdns.net". Message that my users get is "unrouteable mail domain [email protected]", and in the other side, when [email protected] tries to send an email to one of my customers, the [email protected] owner don´t get no error message, simply notice that email was not delivered whet he ask to my customers by phone.
When I aks to my server technical service they told me that problem is located in destiny domain but exampledomain.com technical service tolds me that mistakes are taken place in my server.
