[Dovecot] Problems with dovecot/sendmail combi.

[Roger Berger]

Hi,

I am really stuck here. I am trying to setup imap for an external mail server. I have a freebsd server running sendmail / dovecot. I am transfering the existing mail from an exchange 2003 server to the mailserver using imapsync. This works fine, but gives errors when it tries to make a submap, also thunderbird gives an error "Mailbox doesn't allow inferior mailboxes" when I try to make a submap. I found out that it has something to do with the mbox not able to have submaps and there should be a workaround using namespaces. I tried several setups but keep getting errors. Does anybody know how to configure namespaces to allow submaps?
