Oliver, it was you that reported:

| If quota (expanded) is set to 0, quota should be inactive. Exim creates a
| maildirsize file with '0S,0C' - an IMAP server (I tested courier-imapd)
| treats that as 0 bytes, 0 mails - not as unlimited.

|
| In my opinion if quota is unset no maildirsize file should be created -
| that would fix this bug (at least with courier-impad, maybe others).


So I have two people telling me two different things. :-(

Until this is resolved, I think my best plan is not to make any
change...
