clustering ??

[Fran�ois Philippo]

what does exactly mean clustering with Qmail ?

- 2 servers redondant with a load balancing which accede to the same disk
system
or
- 2 differents servers where each one stock half of mailboxes with a
multiplexor who reroute user request on the good server following LDAP
attribute or a table?
or
- something else ?
