Hello,
I'm a recent convert to dovecot from courier-imap and the performance has certainly improved. I'm running the vanilla 1.0.7 version that came with the CentOS 5.2 x86_64 distro.
I've come across a similar problem that was posted by Ralf Hildebrandt earlier this year under the same subject, but that thread just seems to have died off. I'm also using per- user maildirsize files (originally run under courier-imap) but these are not being read/enforced/updated for some users.
After some testing with these users, the problem seems to be related to the size of the maildirsize file itself. A file size greater than 5119 bytes results in no quota for the INBOX of the user, and the file seems to be ignored entirely by dovecot.
If the maildirsize is >= 5120 bytes the quota is recalculated and a new maildirsize should appear. But there should be a quota, of course. Anyway I never seen that behaviour. Can you upgrade to a recent (1.1.something) dovecot version and see if it happens also?
