America Online runs the world’s largest electronic post office, processing more than 1 billion pieces of email every day, with 34+ million AOL members logging more than 1 billion hours online per month. AOL knows technology.

AOL recently began migrating portions of its mail systems to a Red Hat Enterprise Linux architecture. Migrating to Linux has provided AOL with substantial savings in infrastructural costs in the first year of the migration, while improving network performance and building a flexible architecture for future growth.
