Scalable e-mail systems? (Score 3, Informative)

Try Googling for "Scalable E-mail Systems" and "Scalable IMAP services". Of course, I'm biased since most of the top hits are from the slides from the presentations that I've done at LISA 2000, LISA 2002, etc....

My slides relevant to this discussion can be found at http://www.shub-internet.org/brad/papers/dihses/ and http://www.shub-internet.org/brad/papers/sistpni/.

And yes, Nick Christenson has been a long-time friend and co-author of mine.
