I'd be interested in this, too. It might be a nicer way for smaller sites to share between Dovecot and Postfix. CDB is a read-only (C meaning constant) dictionary file designed by DJB. To update it, build a new one and swap. Alternatively, use 2 or more DBs with the CDB having the bulk of information and a smaller dynamic DB first having the day's changes. Then the bulk data can be rebuilt daily overnight.
Another even simpler "DB" would be a directory index. The directory is the DB. The key selects a file name. The data is the file contents. I'll leave it to your imagination how to update it. It could be a simple "small first in line" DB out of 2 or more.

Hello,
I'd be interested in seeing a CDB based backend for the userdb/passdb lookups.
Is anyone working on this? Is there any documentation (other than the wiki Design section and the code itself) on implementing database backends?
thanks
