hi saminda,

I think we have to  clarify the requirement bit more.
The first question is are CC, and BCC adresses web service endpoints?  or
are they normal mail endpoint s which does not send any replay.

if it is the latter case, I think the question you have mentioned(MEP
handling problem) is not going to happen.
since they don't send any replay and only replay we expect from the To EPR

But if it is the former case as I guess we have to handle it at the service
client level. i.e we have to send seperate mail requests for each and every
CC and BCC address.
Just think about the senario where this service use the Addressing. In this
case Addressing handler have to set the "To" header correctly to send it to
the CC and BCC addresses as well.
Further in any case this service can only be an inonly service. otherwise
every recipient will send responses and there is no logic to merge them.
