Qmail-ldap over NFS

[Francois PHILIPPO]

hi all
I test Qmail-ldap over NFS- 1 server QMail-LDAP + server NFS (post locally  exportfs 
/mail )
- 1 server Qmail-LDAP + Client NFS of the first one (post over NFS mount Qmail1:/mail )

--> SMTP                        : OK from both
--> IMAP using Courier-IMAP     : OK from both
--> POP                         : OK from the NFS server
                                  Problem from the NFS client
 From the NFS client POP has no error but can't read (see) mails !!

any idea ?

thanx
