I had that kind of problem more than once. IIRC there were different
reasons why it happened. 1) There were versions of cyrus-imapd which had
somehow broken quota functionality. If you used those version you ended up
with some problems. 2) Using quota -f on a somehow corrupt mailspool
resulted in all kind of funny things. Fixing everything witch reconstruct
first has helped, but I think I still had to run quota -f twice after it
at least with certain versions of cyrus-imapd. The current 2.3.x version
seem to do fine with me.
