Do you need to distinguish between the deferred and non-deferred smtp?
The postfix serverA (out of the box) will simply see that there is no
route to the Internet and defer the delivery of the mail to those
destinations. When the link goes up you can simply do a 'postfix
flush' to empty the queue.

However this won't work if you are using some sort of dial on demand
which would be triggered by postfix's first attempt to deliver
"Internet mail" by smtp, and you want to avoid this type of traffic
triggering the connection to the Internet.
