"Cluster aware"? That's a new one to me.
If I had a cluster of systems, I'd designate one to be the mailhub and
install a normal qmail on it. The rest of the nodes would be null
clients; forwarding all outgoing mail to the mailhub. Incoming mail to
all nodes would be redirected to the mailhub via MX records.
For reading, I'd deliver everything to maildirs on the mailhub. I'd
run POP and/or IMAP for remote access, and/or NFS-mount user home dirs
on the nodes for "local" access.
If you require lots of redundancy, each node can be a full mailhub and
MX backup for all the other nodes provided you NFS-share user home
dirs among all nodes.
Is that cluster awareness?
