I don't know anything about PowerMTA, but I know that you could get
considerably higher performance than Exim from different
architectures. Exim has one process spawned per concurrent delivery
attempt. This is kind of like Apaches pre-fork mpm where there is one
process per concurrent HTTP response. An MTA which uses an event model
based on something like epoll, depending on the OS, could perform much
better.
