[Dovecot] possible quota bug ?

Hi,

I'm using dovecot 2.2.5 with quota (maildir backend), zlib and expunge plugins.

When I list maildirsize file, I get:

1073741824S 17952 16

If I receive a new message (example: 1204 bytes compressed and 2524 bytes plain text), the quota file is write correctly (2524 1 entry). When I move the message to trash folder (or between user custom folders) the file have wrong entries:

1073741824S 17952 16 2524 1 1204 1 (this is the size of the compressed message) -2524 -1

I coudn't find any relation with the config settings causing this problem and checked the changelog since 2.2.5. Had someone had this same problem?

Thanks, Fernando
