Hi, I have a problem that apparently is related to Symantec (i use symantec endpoint use v11).
 
I have a user who repeatedly get invalid or delay delivery mails.
 
The message is as follows:
 
==================================================
X-Symantec-Messaging-Gateway-Queue-ID: E2/10-03370-59193B05
X-Symantec-Messaging-Gateway-Sender: rfc822; user1@example.com
Reporting-MTA: dns; mailsecurity.example2.com

Final-Recipient: rfc822; user2@example2
Status: 4.4.1
Action: delayed
Last-Attempt-Date: Tue, 27 Nov 2012 12:06:13 -0300
Diagnostic-Code: smtp; 451 4.4.1 [internal] No valid hosts (too many connection failures)
===================================================
 
What might be happening?
 
Thanks!
