cyrus moving mails with a MUA

[Peter Hamtal]

This is what the debugging log shows:

<1166074030<DONE
>1166074030>14 OK Completed
<1166074030<16 uid copy 734 "INBOX.SPAM"
>1166074030>16 OK [COPYUID 1166071366 734 4] Completed
                                          ^^ Is this the permission
setting ? If then why is it set to __4__ ?
Where do i find some hints for the debugging log and how to read it ?

<1166074030<17 uid store 734 +FLAGS (\Deleted \Seen)
>1166074030>* 151 FETCH (FLAGS (\Deleted \Seen Junk) UID 734)
17 OK Completed

imapd.conf is setting umask like this:
umask: 027
