Maybe one could have a switch to turn hosteddomains on and off? I agree with the OP that it is a bit cumbersome to maintain it if everything else can be stored on in DB...

A couple of comments to this: 1) Currently (correct me if I'm wrong Sam) courier has nothing to do with the database - that's all contained by authdameon. Don't think it would be that easy a change - it's not like it's half way there... Direct file access can be WAY more efficent for a number of things - and by it's nature at present it's cached for the lifetime of the courier process...

2) It's REALLY easy to produce all of the control files - including aliases - from your database... it's just a select statement. I can't give you the code as it would be meaning less without the database schema, but it's just a select statement dumped to a file. We trigger this when our mail config data tables are modified to automatically rebuild the files, and then restart the courier process...

In a perfect world, everything would be in a database and fully text indexed and searchable... but not yet...

my 2 pennies.
