Sendmail is the actual MTA that determines the speed of delivery.
When messages are distributed, they are bundled up and dropped in
the sendmail directory for processing/delivery. This is where
using a tool like bulk_mailer help. It will break the bundle into
smaller pieces for sendmail to deliver more in parallel instead of
serially.
