replication notification with chroot users

[Tim Kuijsten]

I'm getting the following error when using dovecot replication:
dovecot: imap(foo at bar.com): Error: 
open(/var/dovecot/replication-notify-fifo) failed: No such file or directory

I guess this has something to do with the fact that every user is 
chrooted in it's own homedir. Does dsync support dsync notification when 
all users are chrooted? lmtp does not seem to have this problem so new 
mails get replicated, but status changes don't.

Thanks.
