Question:
Please correct me if I am wrong.
What I think you need is a queue channel. Your receiveEmailChannel should be something like:
<int:channel id="recieveEmailChannel">
<int:queue/>
<int:interceptors>
<int:wire-tap channel="logger"/>
</int:interceptors>
</int:channel>
Which I'm sure you'll know is how you define a queue channel. The point to point channel which is what you have currently is synchronous it can only have 1 message passed at a time.
Currently if you'd add something to that channel it would wait until the service activator has finished whilst with a queue channel the service activator should fire off a new thread as soon as it detects something in the queue.
