Here we use qmail without any problem, just setting a redirection with
ipvadm :
ipvsadm -A -t xxx.xxx.xxx.xxx:25
ipvsadm -a -t xxx.xxx.xxx.xxx:25 -R yyy.yyy.yyy.yyy
ipvsadm -A -t xxx.xxx.xxx.xxx:110
ipvsadm -a -t xxx.xxx.xxx.xxx:110 -R yyy.yyy.yyy.yyy
where xxx.xxx.xxx.xxx is the IP address of the director and yyy.yyy.yyy.yyy
the address of a realserver running qmail over tcpserver.
Another point is that we use NFS to share the users mailboxes between each
realserver.
At next we use mysql to share user accounts with each realserver from a
database server (the qmail version we use is a patched version). But we
cannot use a database per realserver, as said in the LVS docs, because only
one server could accept writing requests in a such configuration.
In the documentation of mysql, they say they plan to have a solution of
replication which can support more than one master with mysql version 4.
