Question : Can send and receive internal emails and can send external but cant receive external emails.

Hello,
I really need help. company that i work for completely lost access to email, it happened to be that our email host, company that has our MX or A record ( not that familiar with this) drop us without telling us which cause our exchange server to not receive any external emails. We just moved all of our information and transfered it to Dotser.com. well now we do receive limited external emails. but none from AOL or other valid corporations. for example i got a bounce back that my wife sent me while trying to email me directly.

This message was created automatically by mail delivery software. A message that you have sent could not be delivered to one or morerecipients.  This is a permanent error.  The following address failed:   .com>: Cannot find OUTBOUND MX Records for domain (empireresources.com)

and i just found out that alot of our customers are getting the same bounce back, hotmail, yahoo email do come thru.
please help.

Answer : Can send and receive internal emails and can send external but cant receive external emails.

dnsreport.com is showing that you have MX records.
However if you have just changed them or updates your host and name servers then this can take 48 hours to fully propagate. The major ISPs use caching, so changes may not be live immediately.
