[exim] Tools for SQL export to CDB

Folks,

Does anyone have experience with / a recommendation for..

.. tools or settings for exporting records from an SQL DB to a
CDB? (or similar Berkeley or GDB, even?)

The records in question would contain:

- UID

- PWD, crypt and/or plain

- aliases

- virtual domain.tld

- mailstore type and path-to

- per-user & per-domain preferences, such as integer spam thresholds

- white/black lists by IP, domain.tld, HELO, other regexp


IOW - "The usual suspects" w/r Exim's needs.....

Process of export needs to be handled by triggers/
stored-precedures and/or piping via external scripts so as to
support automated updates.

Thanks,

Bill
