Hi,
Thank you for posting here.
From your post, I understand you encountered the mail flow issue when youdeliver messages from a CRM system, and event 4006 appeared.
"Message delivery to the host 'IP address' failed while delivering to the
remote domain"
If I'm off based, do not hesitate to let me know.
Before we go any further, I would like to confirm the following information
with you:
1. Please let me know the recipients, these emails sent to internal
recipients or external recipients?
1. Please let me know which queue the messages are queued. You can refer to
the following Microsoft Knowledge Base article to check this information.

http://support.microsoft.com/?id=823489
2. Based on my research, the event error 4006 may happen when Sybari
Antigen or Symantec/Norton Corporate 9 Internet Email Auto Protect. If you
have this application or similar products installed in Exchange Server,
please temporarily uninstall it and verify the issue. If it persists,
please continue with next step.
3, The issue may happen when the smarthost in Exchange Server points to a
wrong or non-existing server, please verify the setting by the steps below.
4. Use telnet utility connecting to the problematic destination server and
send a test mail to the problematic recipient again. Does it work? Can the
recipient receive the test mail? Send the test results to me.
For more information, please refer to the following article:

5. Enable Diagnostics Logging on the Exchange server.
1). Start Exchange System Manager.
2). Expand "Servers", right-click "<Your_ Server_Name>", and then click
"Properties".
3). Click the "Diagnostics Logging" tab, and then click
"MSExchangeTransport" under "Services".
4). Under "Categories", select all options, and set the Logging Level to
Maximum.
5). Reproduce the problem, after the problem occurs, save the Application
and System log files as .evt files and send them to me at
v-chacez@xxxxxxxxxxxxxx Let me know the recipients and sender's email
addresses.
