Hi Andrzej,

thanks for your replies.

I don't think I'll take this route, but for completeness' sake, that's not 
the kind of hashing Cyrus uses ... I guess you'd actually have to read 
mailboxes.db to find out where a given user's folder is.

I don't think that's feasible.

I'd be OK with that.

If I understand Ken correctly, standard Cyrus 2.2.3 supports this. It's not 
necessary to use a version from CVS.

> b2) using custom "socket map" daemon

I'll have to think about that some more. Migrating to Cyrus 2.2 is on my 
TODO list anyway. I guess I'll build a patched sendmail and play around 
with the socket map feature.

I suppose I'd leave these two rules out, there are no system mailboxes.

Could you elaborate on that? What exactly is the problem?

Thanks, Sebastian
