backupd and sync_client IOERROR

Hello,

I copied the content of the failing mailbox into another mailbox with a 
name without dots:

	springsteen at example.com

and the result is the same:

# sync_client -A -n bck -z -v

USER springsteen at example.com
MAILBOX example.com!user.springsteen
Error from do_user(springsteen at example.com): bailing out!

Instead, if I do:

# sync_client -n bck -z -v -u springsteen at uc.csi.it

USER springsteen at example.com
MAILBOX example.com!user.springsteen
MAILBOX example.com!user.springsteen.#splitconversations
MAILBOX example.com!user.springsteen.ALLARMI
MAILBOX example.com!user.springsteen.ALLARMI.John
[...]

the program replicates as well and without any errors.

At this moment I don't have a normal replica server yet. I'll try...

Thank you very much

Cheers
