qmail Clustering

[Joomy Studio]

Hi all,

Just 4 Questions,

1. Are there any archive of qmail-ldap ?
2. How qmail-ldap works on clusting ?
3. Are there any balance dir creation for user's home dir ? like vpopmail or
vmailmgr
4. Can I use qmail-ldap + CourierIMAP with auth ldap from the same ldap of
qmail ?

I'm setting up 200K POP3/IMAP/qmail users.
pls. help.

Thanks in advance.
