I cant figure out how to receive mails from the same mail domaine

[jjvvoss]

I have a customer, who have a webservice hosted outside the internet.

This Webservice are sending mails to my customer from ie"webservice.xxxx.com to mail.xxxx.com

and its not passing the Ironport email ....

Somebody have a solution ?

it's a bit vague here, but I guess what you are saying is the mails sent from webservice.xxxx.com to mail.xxxx.com where both are the same domain are not getting received at mail.xxxx.com (ironport ESA).

Question:

1. What did the ESA mail log say when tracing the mails sent from webservice?

2. Is there any anti-spoofing mechanism (filters) that blocks or drops the mails received from outside but having the same domain name currently activated?

Hopefully having the answer from the question above could be a good point to start the investigation.
