Which version of Cyrus IMAPD

[marc.bigler at day.com]

Do I need to activate something during the compilation (configure) or is it
per default enabled in 2.1.11 ?

Regards
Marc

Its an improved database backend that is optimized for enumeration, which
happens a lot with the mailbox list.

Berkeley DB is not optimized for enumeration, and while flat can give you
fast enumeration, it is tremendously slow to update.
