Ferris Newsletter: Sun Email #1 Largest on Planet!

Wow.. this is cool to hear

The following was taken from David's "Ferris Newsletter on Messaging & Collaboration, November 2005"

The World's Largest Email Systems. Here's our estimate of the world's largest email systems, measured in number of active mailboxes, as of 10/05. By "active" we mean: has been accessed at least once over the last 30 days:

\* Sun-150M seats !!!
\* OpenWave-100M seats
\* Hotmail-100M seats
\* Microsoft Exchange-100M seats
\* Critical Path-60M seats
\* AOL- 80M seats (including free seats)
\* Yahoo-40M seats
\* IBM Notes/Domino-25M seats
\* Google Gmail-20M seats
\* Novell GroupWise-10M seats

"It's hard to have much certainty about these figures. Almost all vendors severely exaggerate with the statistics they hand out. This is our overall sense of real deployed seats." - David Ferris
