I agree with this choice : the best way to do it is to configure your 
MTA for that.

That's true until version 6 (which is not yet available). In this 
version, the bulk mailer is completely reconfigured. One of the goal is 
to be able to stop and restart Sympa during a huge distribution process 
without message duplication. It is also possible now to start the 
distribution of a new message with hi priority without waiting lower 
priority distribution process to finish.

We want also best performances and scalability
