We are evaluating the possibility of using cyrus for a commercial product. Therefore, I'm looking licensing issues with Cyrus and the Berkeley DB product must be licensed if the source code of the product using it is not provided. The license depends on which Berkeley DB product you are using. Does anyone know which of the below Berkeley DB products cyrus is using? Cyrus, by default, uses the Berkeley DB transactional data store. The data stored in it needs to be persistent through reboots and other failures. [...] Is cyrus dependent on Berkeley DB or fairly easy to remove the dependency or replace it with another DB? Cyrus is only loosely dependent on Berkeley db; in fact, for 2.0.16, it can be trivially configured to not even use Berkeley db. (Edit "cyrusdb_db3" to "cyrusdb_flat" in imap/mboxlist.h.) It should be straightforward to write an alternate database (look at lib/cyrusdb_*). The duplicate delivery database is also Berkeley db dependent, but this isn't as easy to change in 2.0.16. It'll be somewhat easier in 2.1. The next version of Cyrus will utilize Berkeley db tables somewhat more heavily. Larry
