Can you explain further what you mean by a "processes' bandwidth
usage".  The process-related information collected by the kernel is
listed in getrusage(2).  You might also like to look at ktrace(1,2).
I suspect you may need to modify the kernel to capture the information
you are looking for.

an MTA that is either RFC2821-compliant or matches their claimed behaviour.
