One more note on this.
vpopmail uses user quotas as specified in the vpopmail
password entry, not the maildirsize file.
courier and other maildir++ quota compliant code uses
the quota as specified in the maildirsize file.
So if you change the quota via qmailadmin or vpopmail utilities,
it will update the quota in the password entry. This is what
vpopmail uses to enforce the quota, not the one in maildirsize.
If you just "remove" the maildirsize file, it will automatically
be recreated (with the proper quota in it).
So it may be worth a patch to update the utility that updates
the quota to also remove the maildirsize file for that user.
