Thanx peter and sapta
However you guys have answered only the part three of the question. I would like to know the first two questions as well.
#1. What is happening?
#2. Why it's happening
#3. What is the resolution so that messages pass thro successfully. (Probably answered)
Symantec administrators...
probably you shall be able to give the answer to the first two questions. Getting answers to those shall improve our understanding on the architecture. And I guess, that should be the main purpose of this forum, rather than just getting the workaround of the reported issues/concern/problem.
