   Indeed, does someone have an answer for this question?  Everyone seems
   to be avoiding it :)

   Can Cyrus handle storing mailboxes to an AFS drive?

No. CMU's previous e-mail system, AMS, leveraged AFS extensively for
storage (and transit) purposes. For various reasons it didn't scale
particularly well and led to CMU's interest in IMAP.

Cyrus was designed to use a local filesystem with Unix semantics and a
working mmap()/write() combination. AFS doesn't provide these
semantics so won't work correctly.
