Dbmail will run on pretty much any platform that supports GCC, autotools, and libtool. So yes, redhat whatever is/should be supported without any trouble.
Loadbalancing is more tricky. There are two main bottlenecks in the current setup: - concurrent connections; the total sum of running dbmail processes and hence concurrent client connections is determined by the sum of connections your database cluster will support. There is at present no mechanism for connection pooling. This is planned for the 2.3 developement cycle. - multi-master sql backend replication; the size of your database cluster is limited by the fact that limitations in the imap protocol will not allow multi-master replication out-of-the box. Insertion of new messages will have to be done in order of arrival acros the whole installation. The algorithme to remedy this has been discussed in depth, but implementation is not planned at the moment. Both issues are documented on the wiki pages. Probably the best route for scalability and loadbalancing is by distribution of mailboxes accros several database clusters, and by redirecting imap clients to the correct cluster by using imapproxy. Of course, insertion will also have to be redirected and shared mailboxes are limited to a single database cluster.
