Hi, it looks like there is a bug (in dovecot or in my config) with quota on maildir mailboxes when accessed via POP3.
The maildirsize is not created when not already present (even after a DELE + QUIT command). The quota limit (the first line of maildirsize) is not updated if values are not in sync with those in the database. If maildirsize is present, DELE commands are correctly reported in maildirsize.
maildirsize is correctly updated when the same mailbox is accessed in IMAP or mail is delivered with dovecot LDA.
Here is my config. Timo 'dovecot -n' does not show the lda config part...
