Hi
Throughout the v. 1.1 betas I have been receiving casual reports that quota isn't handled correctly (running Maildir).
At the moment I'm running 1.1beta14 but this has been occurring in all other 1.1 betas as well (I don't know for sure whether this was also an issue in 1.0, but I think so). In some earlier betas the issue where worse than is is now (due to improved NFS locking I guess).
Apparently this occurs when the user shifts between pop3 and IMAP. maildirsize gets updated whenever mails are coming in, no problems there.
But mails removed aren't always counted as removed - as a result some users quota keep growing until they reach a limit and e-mails start getting rejected.
I have been doing some testing and it appears that the updating of the file maildirsize is sometimes delayed. I figure this is because Dovecot collects theese changes in the transactions or index file and then once in a while writes them to maildirsize.
Could there be a week spot in the code somewhere that allow for this kind of error when the use of POP3 and IMAP are mixed (I think this happens even when POP3 and IMAP access aren't concurrent)?
Both my index files and mail storage are located on NFS.

This is the output of dovecot -n:
