Oh, and you probably don't even want to think about what we did for our
Dovecot infrastructure. Clustered NFS servers with seamless failover,
snapshotting, and real-time block-level replication aren't cheap. The
students and faculty/staff not supported by an existing Exchange environment
aren't getting any less support, I'll say that much.

Folks trust us with their education, their livelihoods, and their personal
lives. I'd like to think that 'my fellow taxpayers' understand the
importance of what we do and appreciate the measures we take to ensure the
integrity and availability of their data.
