I'd prefer to see both.  Many of us already have substantial investments
in Cyrus installations ("investments" being expertise using it and
having installations where migration would be non-trivial).

However, Dovecot is very appealing and would fit a different problem
domain than Cyrus.  Dovecot, from what I can tell, should be mailbox
compatible with UW-IMAP, which Cyrus definitely isn't, so upgrading a
small site to Dovecot should be easy.

On other hand, Cyrus has a number of advantages, especially for large
sites:
  o Multiple partitions to accomodate growth and performance tuning.
  o Clustering with Murder.
  o Squatter back-end indexes, which make mailbox searches very fast.
  o Skiplist databases, which are fast.
  o LMTP delivery (don't need to run an MTA on the IMAP server).
  o Single-instance store.
  o Virtual domains.
  o Sieve filtering (less flexible but considerably faster than
procmail).
 
And finally:
  o Fairly long term commitment by a stable organization.
  o Mature, widely-used and tested codebase.

The last two aren't meant to be slams on Dovecot; it's development
structure is unknown to me, but these I do know about Cyrus.
