I have a customer that host their website with me. They do not want to use my server for their email, instead, they need a MX record pointing to a different IP address. Currently, all email sent to them bouces. Here is what I have setup:
@ 14400 IN SOA ns3.hosting.com. andy111.sympatico.ca. (
customer.com. 14400 IN NS ns3.hosting.com.
customer.com. 14400 IN NS ns4.hosting.com.
customer.com. 14400 IN NS .
customer.com. 14400 IN A ###.67.248.107
localhost.customer.com. 14400 IN A 127.0.0.1
customer.com. 14400 IN MX 0 customer.com.
www 14400 IN CNAME customer.com.
ftp 14400 IN A ###.67.248.107
mail 14400 IN A ###.204.188.149
Am I missing something here? Could it just be that DNS has not propagated all the way?
