The version shipped with RedHat 7.2 has worked very well for me. In fact
much better than the one from 7.3. My config looks like this:

name       : Cyrus IMAPD
version    : v2.1.9-Invoca-RPM-2.1.9-4 2002/08/30 18:40:23
vendor     : Project Cyrus
support-url: http://asg.web.cmu.edu/cyrus
os         : Linux
os-version : 2.4.9-34SGI_XFS_1.1
environment: Cyrus SASL 2.1.5
             Sleepycat Software: Berkeley DB 3.2.9: (January 24, 2001)
             OpenSSL 0.9.6b [engine] 9 Jul 2001
             CMU Sieve 2.2
             TCP Wrappers
             mmap = shared
             lock = fcntl
             nonblock = fcntl
             auth = unix
             idle = poll
             mboxlist.db = skiplist
             subs.db = flat
             seen.db = skiplist
             duplicate.db = db3-nosync
             tls.db = db3-nosync
