There is no such thing as a simple MTA. This gets hairy quickly. Really quickly.
Bryan is one of the few people I would expect to be able to do something that could actually handle the easy 80%. Writing the book _sendmail_ (now in its fourth edition) is just one of his many talents.
you are much better off spending money on a good fast disk RAID (since the chances that you'll win the lottery are on par with the chances that your bottleneck is NOT disk I/O in mail sending) than on a programmer to try to build fast MTAs.
They were already using pure RAM disks for this application. Disk I/O was not the problem.
Bryan and Eric were two major contributors to my invited talks "Sendmail Performance Tuning for Large Systems" (see <http://www.shub-internet.org/brad/papers/sendmail-tuning/>) and "Design and Implementation of Highly Scalable E-mail Systems" (see <http://www.shub-internet.org/brad/papers/dihses/>). These guys are not lightweights in this field.
And boy, does it show.
Indeed.
