Hi Timo,
Thanks for your quick response, apologies for my slow one.

I noticed an interesting bit of information doing this: the users that
are having a problem have no dbox-Mails directory in their
source mailboxes/INBOX directory - but on the destination where I am
sending the backups, there is one. If I remove the backup's INBOX/ and
then re-do the dsync, things work again.

I have no u.* files on either side. There are m.* files though?

did you mean s/sdbox/mdbox/ here?
also, I was using 'backup' and not sync, I dont know if that matters?
I tried this with some that had issues, but I couldn't reproduce the
error this way :p

I'm working on getting a newer version of dovecot installed to test
this.

if this happens: http://hg.dovecot.org/dovecot-2.2/rev/8146fdc0de34
great, this will certainly be helpful!
