Could you verify that this db4 package has the two official sleepycat

Does anything use this one? ldd the cyrus-imapd binaries to make sure
you are not using a mix of different DB4 versions.

Do you have a DB_CONFIG file in /var/lib/imap/db/? It's needed for some
installations. I have one with the following, it may get you started:
# Sample BDB configuration file.

set_cachesize 0 524288 1
# buffer size for transaction log

# set_lg_dir: configure a separate directory for the transaction logs
# For optimum performance, these should reside on a different disk

# set_lg_max: configure the maximum size of the transaction log file, in bytes

# Note that lg_max must at least be 4x the size of lg_bsize. The default is 10Mb.
