kolab slave server problem

[Antonio Straziota]

Hi guy,
i've some problem with kolab slave.

I use it as a internet webmail, but when i try to send email, i get an
error (The folder "sent-mail" was not created. This is what the server
said: Permission denied) followed by "Message sent successfully, but
not saved to sent-mail". Actually the sent folder exits (because i
created it on master kolab) and the mail wan't sent.
In addition, when i access users mailboxes, i can't see their mails.

Any idea?

on both master and slave I've Centos5.2 and kolab 2.2.0

Thanks in advance.
